455. THE IDEA OF SOLICASTER BY RORY HOFFMAN

 https://www.youtube.com/watch?v=KUBZB4jDqW0&ab_channel=RoryHoffmanMusic

In this technique we utilize mainly 3 notes chords of the 3 highest strings of the guitar in such a  way that

the highest note and string is always the note of the melody, and in particular a melodic center (the other notes of  the melody are played but with no underlying chord necessarily.

454. A CHORD AS A GROUP OF MODULATION-VARIATIONS OF MELODIC THEMES OVER THE CHORD.

  A CHORD AS A GROUP OF MODULATION-VARIATIONS OF MELODIC THEMES OVER THE CHORD. 


The elements of  the group are modulations-variations, and the generators of the group are defined by the intervals of the chord. The exact definition of the variation of a chord-fitting melodic theme is such that it holds group closure to the operation of composition of variations. E.g. idempotent  a^2=1, where repeating a shift by an interval is with its complementary interval .


The most relevant layers of the melody is the 1st layer of simplicial submelody, and  the 2nd layer of the arpeggios over the chord. 

The part of a poetic measure corresponding to a chord, is of course a guide too.

453. WRITTING A MELODY OVER A CHORD PROGRESSION AS IF WRITING A POEM WITH SYLLABIC METER.

 

This idea is mainly the one described in 8-bars blocks songs in previeous  posts .

The first 4 bars, have 2 chords one per 2 bars, and the  chords and melodic themes as well

have the pattern of the 8 bars 


Chords          A  A   B  B

                      A  A   C  C


Now each line of 4  bars (AABB, or AACC) may be conceive as a poetic line

e.g. of 15-sylables poetry .

452. THE MOST CONVENIENT MUSICAL INSRTUMENTS TO IMPROVISE OR COMPOSE THE 3 LAYERS OF A MELODY.

 As we have remarked (see posts 450 447) the melody has 3 layers


1) 1st layer The 1st simplicial submelody or chord progression

2) 2nd layer The 2nd simpicial submelody or arpeggio

3) 3rd layer The chromatic ripples.


A) The 3rd layer because it is mainly waves by intervals of 3rds is improvised best or composed on the fretboard of a string instrument (including violin) but also with the slide of a trombone. With digital instruments my favorite is the digital chromatic harp Thumbjam and of course the piano keyboard.. Harmonicas with cyclic tuning are also  convenient

B) The 2nd layer, is best improvised or composed with a string instrument which plays chords (ukulele, guitar etc) and especially if it is tuned with an overtones tuning system like on Dobro guitar. For digital such string instruments my favorite is the Geoshred. But if the melody is diatonic it can be with the 2-dimensional Musix Pro.

C) The 1st layer are the bridges of the chord transitions. The most convenient instruments are again the string instruments that play  chords (ukulele, guitar etc) bass instruments, but also the digital chromatic harp and of course the piano keyboard.

451. THE 4 BASIC DIATONIC CHORD TRANSITIONS AND THEIR ORDER OF BEAUTY.

 

1) As it known the most common and most often used due to its beauty is the harmonic chord transition 5M7->1M. It is a relaxing resolution. Ii is strictly diatonic transition.


2) The 2nd best in beauty chord transition and also widely used both in classical and fol music is the melodic chord transition to the major relative chord. Thus the 1M->6M7 (or 4M->2M7, or 5M->3M7).It is not directly a diatonic transition but in the general context of chromatic diatonic transitions. It is a tired resolution. 

3) The third best chord transition is  the melodic chord transition to the lower minor relative chord, e.g.

1M->6m (or 4M->2m or 5M->3m) . It is a easy slip  to sadness

It is  directly a diatonic transition.

4) The 4th best chord transition is the chromatic chord transition e.g. 1M->2m

450. THE 2nd SIMPLICIAL SUB-MELODY AS ARPEGGIO AND THE 3-LAYERS FULL MELODY AS EXTENSION OF IT WITH WAVING BY INTERVALS OF 2NDS (CHROMATIC)

In previous posts we have defined an at least  2 layer structure of melodies. The 1st simplicial sub-melody where  for each chord there is one note of it/ The chord relation usually are translated to intervals among the notes of the 1st simplicial sub-melody. Nevertheless if the chord sounds for many measures (bars) as e.g. in 12 bars Blues, then we may have a 3 layer structure of the melody and a 2nd simplicial sub-melody with notes inside a chord which are essentially an arpeggio of the chord To  this we add the 3rd last layer of chromatic waving mainly with intervals of 2nds (tails) . This 3-layers structure of the melodies and the corresponding 3-speeds in a melody ( harmonic, melodic (arpeggios) , chromatic(tails)) is the key to understand but also to compose beautiful melodies 


 For example for Aegean islands (Greece) improvisational folk melodies (mandinades) condylies) with violin or Lyra, the next factors prevail.

1) "Poetic meters" over the same note sometimes notes up to 8 notes. The density of the notes is high. E.g. with 4 notes per  measure-bar and a beat of 80-100 bars per minute gives a tempo of 320-400 beats-notes per minute.

2) Straight vectors ascending or descending usually of 4 or 5 notes so as to reach a new chord neighborhood.

3) Mainly waves by intervals of 2nds (chromatic) inside intervals of 3rds (melodic, either standing or ascending descending, and usually inside a chord  so as to reach the neighborhood of a new chord. The simplistic sub-melody of such a waving melody is essentially an arpeggio of the underlying chord.

4) The overtones tuning of string instruments and the way the  trombone and in general brass instruments functions are perfect matches for this general melodic -chromatic structure of the melodies in improvisations. Similarly for the melodic-chromatic 2-dimensional arrangement of notes in the Music Pro.

449. METHOD OF COMPOSITION OF SONGS BASED ON THE 16 BARS BLUES 16BB or 32 BARS BLUES 32BB RHYTHMIC-HARMONIC PATTERN

 The general  rhythmic harmonic pattern of 16 bars blues denoted by  16BB is the next


Let X1 X2 X3 be an harmonic triad of chords , in other words consecutive in the wheel by 4ths. They may be major or minor chords then the general 12 bars blues rhythmic-harmonic pattern is the next 


X2X2X2X2
X2X2X3X3
X3X1X3X1

X1X1X2X2
Or if we have 2 beats per bar and we want to preset it per beat (or alternatively as 32 bars blues) then




This more detailed presentation gives us the opportunity to make subtle variations of the rhythmic pattern like the next 








Still another pattern of 16bars Blues that is often met in  New Orleans jazz songs by the group Tuba Skinny

is the next 

1M  1M  1M   1M

4M  4M 1M  1M

1M 1M   1M   1M

5M7  5M7  1M   1M

The melodic themes follow the pattern of the 4 lines of the block . That is the pattern A B A C.


In the general scheme we might allow for any arrangement of X1 ,X2 X3 on he above squares

If the Xi  X1 X23 are major denoted by M or minors then we have 8 types of such general 12 bars blues rhythmic-harmonic patterns


MMM

MMm

mMM

MmM

mmm

mmM

MmM

mMm

A usual rhythm is 120 bpm and 4 beats per bar. This gives that one such 16BB has duration about 30 seconds thus about 6-8 repetitions of this 12BB pattern will give a song a little less or more than 3 minutes duration.

Now the general concept of composing sings based on the 16BB patterns is based on the next

a) We start with a 16BB as unit block and we modulate it or transpose it about 6 times

b) We alter the 16BB pattern substituting any of the instances of each of the Xi chords i=1,2,3 with relative minor or major chords.


The difference in easiness and familiarity when composing songs based on thsi method compared to no method, is as the difference of walking by feet compared to moving by a car (the car=12BB pattern)

In the guitar such an improvisation is mostly easy if the guitar is tuned in one of the open overtones tuning. E.g. Open D tuning. 


In order to create the melody we may proceed as follows.

1)We compose 2 or 3  simplicial sub-melodies one for each part of the song ,  with one note per chord and bar (strictly speaking the 1st simplicial submelody with one note per chord and the second simplicial submelody which is also an arpeggio, with one note per bar inside teh chord) , over the cycle of chords preferably at a chromatic sequence ascending and descending .  In this way we may have more than one note of the simplicial sub-melody per chord but only one per chord and bar.  This involves that we compose the orientation  of the melody inside the chord, up, or down or waving. 

2) We create moves or waves or cycles for each note of the simplicial sub-melody by sequencing during the chord with two types of notes a fast (usually outside the chord) and a slow of double duration on the notes of the chord again ascending or descending with smaller waves. I this way more than 50% of the time of the duration of the melody will be notes of the chord. This means that we apply a "poetic meter" in the melody, here the trochaic which is also the swing and vals. If we use keyboards (and this may also be e.g. digital harp in the tablet as in ThumbJam)  , the way to create the melody is the next. For each  lines in the 16 Bar Blocks which is usually a  pair of chords , we layout the chords in the keyboard to see their mutual topology and overlapping. Then we compose 5-6 versions of the melody, by one up or down wave within each chord, which are usually one vector-wave for half or full the chord (123 , or 1234565 or 543 for 3-notes chords or 7654321 for chords with 7nth etc in trochaic poetic meter) . We use balancing structure e.g. if the first is up the next is down and vice verse. But two ups or two downs are for emphasis too. We may split the vector-wave to arpeggio and tail or only arpeggio. We choose the version that we like best and expresses best the emotions we want. We use not one only octave necessarily but 2 or even 3. Starting from high, in high octaves and descending down 1 or 2 octaves is a bird-like melodic approach. If we use harmonica the themes waves for each chord or pair of chords are quite more free. If we use guitar , violin , flute, it is more or less as with the keyboard but again a little more free to follow the constraints and conveniences of the instrument.   

3) We may apply the pattern of 4 waves-cycles. Initial idea-variational continuation-contrasting mutation-closure.   E.g. Down cycle-down cycle modulated-up cycle-wave shrinking and ending to middle note. Or vice versa Up cycle-Up cycle modulated-Down cycle-wave shrinking and ending to middle note. Usually this structure copies the the rhythmic structure of the 8, 12 ,16 or 32 bars Blues  It is important to realize that such a  wave or cycle need not be 100% over a chord but it can be over a pair of chords as chord-transition theme (x% over one chord y% over the next x%+y%=100%) and sometimes as themes over three chords. Thus each melodic theme of the 4 phases of it may correspond to 4 bars and the 4 melodic themes may rhythmically correspond to the 4 times the 4 bars (1 cycles of 16BB). Therefore this involves that we compose the bridging transition to the next chord. 


Thus  

X2X2X2X2
=INITIAL POSITION MELODIC THEME
X2X2X3X3
=OPPOSITION MELODIC THEME
X3X1X3X1

=CONTINUATION OF 1ST MELODIC THEME
X1X1X2X2

=CLOSURE MELODIC THEME

4) We arrange a continuous sound instrument to play the simplicial sub-melody only and a discrete sound (guitar mandolin etc) to play the full waves melody.


We may summarize in short

1) We compose the simplicial sub-melody per bar and chord, which defines the orientation of the waves within a chord.

2) We compose the  poetic measure of the melodic themes (long short notes combinations) . When creating melodic themes over the same poetic meter, to remain in the same poetic meter we may repeat a note or we may jump by a melodic or harmonic interval (3rds or 5ths and their inverses). 

3) We compose the bridging transition to the next chord

4) We arrange for continuous sound (simplicial sub-melody and bass) and discrete sound instruments. 


Also at the meso (=medium) and micro layer, the main 4 factors are 

1) Up, Down or flat vector-waving and is meaning (including which octave) 

2) Density of notes per time unit (many notes theme, very few notes theme)

3) Percentage of harmonic or melodic intervals (acceleration) to the chromatic intervals (deceleration).

4) The poetic micro-meter and poetic macro-meter  in the melodic theme.

For example for Aegean islands (Greece) improvisational folk melodies (mandinades) condylies) with violin or Lyra, the next factors prevail.

1) "Poetic meters" over the same note sometimes notes up to 8 notes. The density of the notes is high. E.g. with 4 notes per  measure-bar and a beat of 80-100 bars per minute gives a tempo of 320-400 beats-notes per minute.

3) Straight vectors ascending or descending usually of 4 or 5 notes so as to reach a new chord neighborhood.

2) Mainly waves by intervals of 2nds (chromatic) inside intervals of 3rds (melodic, either standing or ascending descending, and usually inside a chord  so as to reach the neighborhood of a new chord. The simplistic sub-melody of such a waving melody is essentially an arpeggio of the underlying chord.


When making the substititutions it is good to keep the rule of the previous article, that is

 60% harmonic chord transitions, 30% melodic transitions, 10% superchromatic transitions. 

As alternative methods we have that the chord progression of the 12 bars blues can be shifted to all the 7 modes ofthe diatonic scale, so that it can produce different tonal or chrmatic tonal 12-bars blues 


Here are all the 7 modes of the chord progression for the 12 bars blues

IONIAN                  1M 4M 1M 5M 1M 
DORIAN                 2m 5M 2m 6m 2m
FRYFIAN                3m 6m 3m 7d 3m
LYDIAN                  4M 7bM 4M 1M 4M  (chromatic tonality because of the 7b)
MIXOLYDIAN        5M 1M 5M 2m 5M
AEOLIAN                6m 2m 6m 3m 6m
LOCRIAN                7d 3m 7d 4#M 7d  (chromatic tonality because of the 4#)

If we are capturing the diatonic mode with a pair of chords in chromatic relation (in harmonicas it would be an hexatonic harmonica) then the 12BB pattern will give if we have a theme for a single type of chord.

Ionian-Ionian

Lydian-Ionian

Mixolydian Lydian 

Myxolydian-Ionian

If we want a diatonic model per pair of chords then X2 X3 is a Lydian mode and X1 X2 is an Ionian mode, thus

Ionian 

Lydian 

Myxolydian

Ionian


And for hexatonic harmonicas with a chromatic pair of chords  it would be the chords

(3m 4M)= Lydian

(3m 4M)=Lydian

(4M, 5M)=Myxolydian 

(7d 1M)=Ionian 





We may as well utilize 32 bars blues. There are two patterns that I have used for this.

The 1st is the next pattern (see https://www.youtube.com/watch?v=N95yzhLyCcg&ab_channel=DrKCostas ) of one only part 32BB.

1M 1M 1M 1M 1M 1M 1M 1M 1M 1M 1M 1M 5M7 2m 2m 2m 2m 2m 2m 5M7 2m 2m 2m 5M7 5M7 5M7 5M7 1M 1M 1M 1M 1M

The 2nd pattern  is simpler and more symmetric but of two parts of 16BB.

A part

1M  1M  1M   1M

1M  1M 5M7  5M7

5M7 5M7 5M7 5M7

5M7 5M7 1M   1M

and B part

1M  1M  1M   1M

1M  1M   4M  4M                  

4M 4M   4M   4M

4M  4M  1M   1M  or


1M  1M  1M   1M

1M  1M   4M  4M

4M 4M   4M   4M

5M7  5M7  1M   1M

Thus here we have two parts 16BB which make 32BB. 

A type of variation of this  involving the 2m instead of 4M is the next

A part

1M  1M  1M   1M

1M  1M 5M7  5M7

5M7 5M7 5M7 5M7

5M7 5M7 1M   1M

and B part

1M  1M  1M   1M

1M  1M   2m   2m

2m  2m    2m   2m

2m  2m  1M   1M

or 

1M  1M  1M   1M

1M  1M   2m   2m

2m  2m    2m   2m

5M7  5M7  1M   1M


Still another pattern of 16bars Blues that si often met in  New Orleans songs by the group Tuba Skiny

is the next 

1M  1M  1M   1M

4M  4M 1M  1M

1M 1M   1M   1M

5M7  5M7  1M   1M

and in harmonic minor (eolian mode)


6m  6m 6m 6m

2m  2m  6m 6m 

6m  6m 6m 6m

3M7  3M7  6m 6m

also in Phrygian mode

3m  3m 3m 3m

6m  6m  3m 3

3m  3m 3m 3m

7M7  7M7  3m 3m

The melodic themes follow the pattern of the 4 lines of the block . That is the pattern A B A C.

The next video is a well known experiment with many interpretations.
In our case of musical composition we interpret it that the big balls or rocks are the simple but macroscopic factors of a musical piece that should come first . Here are
1) The rhythm and parts of the song (8, or 12 or 16 or 32 bars blocks)
then the
2) the chords
3) simplistic sub-melody or bass
4) The melody etc.

448. WHAT THE LISTENER NOTICES MAINLY WHEN LISTENING TO MUSIC

  WHAT THE LISTENER NOTICES MAINLY WHEN LISTENING TO MUSIC

A listener notices mainly the next factors with the following order due to simplicity of perception


1) The rhythm if it is slow or fast

2) The timbre of the instrument or voice that sounds the melody

3) The emotional meaning of  the melody (sad, happy, resolving to serenity or escalating to tension etc)

4) The structure of the arrangement (few or many instruments etc)

5) The emotional meaning of the harmony behind the melody

447. THE 6 BASIC FACTORS IN THE PERCEPTION AND COMPOSITION OF MELODIC SENTENCE (THEME)

THE 6 BASIC FACTORS IN THE PERCEPTION AND COMPOSITION OF MELODIC SENTENCE (THEME) 

The 6 basic factors are

1) The macroscopic parts morphology of the melody (macro layer) .

E.g.

A1= 1ST IDEA MELODIC THEME OR SENTENCE (INNOVATION) , SYLLABLES 1-4

A2=1ST IDEA AGAIN REPEAT OR VARIATE -ESCALATE (MIMIC), SYLLABLES 4-8

A3=MUTATION-CONTINUATION (ASSIMILATION 2ND INOVATION) SYLLABLES 9-12

A4 =CLOSURE WITH ASCENZA OR CADENZA 

(COMPLETION  INTEGRATION ) SYLLABLES 13-15

We may permute the 4 parts to 

A1= 1ST IDEA MELODIC THEME OR SENTENCE (INNOVATION) , SYLLABLES 1-4

A3=MUTATION-CONTINUATION -CONTRAST IDEA (ASSIMILATION 2ND INOVATION) SYLLABLES 4-8

A2=1ST IDEA AGAIN REPEAT OR VARIATE (MIMIC), SYLLABLES 9-12

A4 =CLOSURE WITH ASCENZA OR CADENZA  (COMPLETION  INTEGRATION ) SYLLABLES 13-15




2) The Quality: Chromatic, melodic , harmonic character of the melodic theme (micro layer) . Analogy of intervals of 2nds (chromatic) 3rds or 6th (melodic) and 4th or 5th (harmonic ) It is the arpeggio-tail aspect of the melodic theme

3) Chord harmony of the melodic theme (micro layer). Order of appearance of intervals of 3rds minor  or major and where, which is essentially the harmony of the underlying chord(s). The 3 notes of the chord symbolize also the 3 types of waves up-ending wave, middle-ending wave , down-ending wave. 

4) Cycles dynamics of the melodic theme (middle layer). Wave-up, Wave-down dynamics or topology of the melody (structure of "Dolphin words" as termed elsewhere in this book). This includes cadenzas and ascents.   Besides the trinity wave-up, wave-down and wave horizontal, we have also mainly a trinity again of further waving. Thus a wave up is very often through 3 sub-waves a) long wave up, b) short wave down, c) long wave up. While a  wave down is very often through 3 sub-waves a) long wave down, b) short wave up, c) long wave down. And a flat horizontal wave is most often through 3 sub-waves a) short wave up or down , b) short wave down or up c) short wave up or down. 

5) Power of 2 micro-rhythmic expansion of the melodic theme  (nano layer, quantitative poetic micro-meter and syllabic poetic macro-meter) . The use of orders of rhythmic speed as powers of 2 (whole, notes, half, quarters, eighths etc). The poetic macro-meter is the constant number of syllables in the lines of a poem (e.g. 15-syllables poetry). This is usually translated in the melody that the melodic-themes bridges of pairs of chords are always of the same duration or number of notes as in the poetry

Usually we may impose a poetic measure or meter (https://www.youtube.com/watch?v=S13Tg3RAUW4&ab_channel=OSUSchoolofWriting%2CLiteratureandFilm) as combination or pattern of long-short notes where the long has double duration compared to the short

E.g. alternation of long-short, is the trochaic poetic measure. (https://www.youtube.com/watch?v=SBTKb5a1gSA&ab_channel=LocalGemsPoetryPress)The long note is in the chord, the short may be outside the chord. In this way we know that the melody fits the underlying chord. The trochaic poetic meter is identical with the swing rhythm of dancing. The word also trochaic in ancient Greek has the same root with the 

wheel= trochos and it means "of the type of wheel". Other poetic measure can be applied as long as they are divided in to two parts of long-shorts, so that one part has longer duration and must be from notes mainly inside the underlying chord, while the shorter part possibly from notes mainly outside the chord. 

6) Instrument's or voice's timbre (super nano layer) . The timbre and nature of the playing instrument (continue sound, string or wind etc) 


When improvising or composing the most important are the nano, micro middle layer and finally the macro layer)


IF WE WANT TO SIMPLIFY IT TO 3 ONLE FACTORS THEN THESE ARE

A) 1) The macroscopic parts morphology of the melody (macro layer)

B) 4) Cycles dynamics of the melodic theme (middle layer). Wave-up, Wave-down dynamics or topology of the melody (structure of "Dolphin words" as termed elsewhere in this book). This includes cadenzas and ascents.  This may include the nano-rhythms in the theme (notes duration divided by powers of 2 or nano-layer)  

C) 3) Chord harmony of the melodic theme (micro layer). Order of appearance of intervals of 3rds minor  or major and where, which is essentially the harmony of the underlying chord(s). This may include percentage of intervals of 3rds or higher (arpeggio parts) and intervals of 2nd (tail parts). 

Also at the meso (=medium) and micro layer, the main 4 factors are 

1) Up, Down or flat vector-waving and is meaning (including which octave) 

2) Density of notes per time unit (many notes theme, very few notes theme)

3) Percentage of harmonic or melodic intervals (acceleration) to the chromatic intervals (deceleration).

4) The poetic micro-meter and macro-metter  in the melodic theme.

WHAT THE LISTENER NOTICES MAINLY WHEN LISTENING TO MUSIC

A listener notices mainly the next factors with the following order due to simplicity of perception

1) The rhythm if it is slow or fast

2) The timbre of the instrument or voice that sounds the melody (is continuous like violin or flute , or discrete like mandolin or guitar etc)

3) The emotional meaning of  the melody (sad, happy, resolving to serenity or escalating to tension etc)

4) The structure of the arrangement (few or many instruments etc)

5) The emotional meaning of the harmony behind the melody

445. The easy method to improvise with a trombone over a known chord progression (e.g. 12BB, 8BB etc)

See also posts 363, 359, 332 


We add here a simple technique to improvise over such 8BB chords patterns  too with the tenor trombone which emphasizes the glissando ability of the trombone..

We must notice that from any note we are in the diatonic scale during a chord there is always a note of the chord at most an interval of 3rd away! 

1) So the method is tho start with an arbitrary note and correct it with the slide by at most an interval of 3rd to a note that fits the chord.

2) When we want  a much higher or lower note during the chord or because the chord changed we just blow harder or softer for a higher or lower overtone (partial) at the same position and then we correct it if necessary with the slide! 

3) The whole process becomes easier if we are on the 3rd octave of overtones where the overtones form the major tonal chord (with a  7nth) . And for this the best idea is to utilize a french-horn mouthpiece for the tenor trombone!

444. THE FOUR VARIATIONS-PARTS MORPHOLOGY OF A MELODY OVER A MELODIC THEME OR SENTENCE THAT FITS TO THE 15-SYLLABLES POETRY

 A1= 1ST IDEA MELODIC THEME OR SENTENCE (INNOVATION) , SYLLABLES 1-4

A2=1ST IDEA AGAIN REPEAT OR VARIATE -ESCALATE (MIMIC), SYLLABLES 4-8

A3=MUTATION-CONTRASTING-CONTINUATION (ASSIMILATION 2ND INOVATION) SYLLABLES 9-12

A4 =CLOSURE WITH ASCENZA OR CADENZA 

(COMPLETION  INTEGRATION ) SYLLABLES 13-15

We may permute the 4 parts to 

A1= 1ST IDEA MELODIC THEME OR SENTENCE (INNOVATION) , SYLLABLES 1-4

A3=MUTATION-CONTINUATION -CONTRAST IDEA (ASSIMILATION 2ND INOVATION) SYLLABLES 4-8

A2=1ST IDEA AGAIN REPEAT OR VARIATE (MIMIC), SYLLABLES 9-12

A4 =CLOSURE WITH ASCENZA OR CADENZA  (COMPLETION  INTEGRATION ) SYLLABLES 13-15





This morphology can be either as melodic themes within a single chord , or as melodic themes as chord transitions or even over 3 chord transitions.

After this macroscopic morphology of the melody we may focus on the intervals statistical frequency in the melody (chromatic, melodic harmonic intervals). The order with which the melodic intervals appear in the melody corresponds to the harmony. 
Here a relevant video



Finally the other factor in the melody is the wave-up wave-down dynamics and the emotional meaning he convey.

THE rest 5 BASIC FACTORS IN THE PERCEPTION AND COMPOSITION OF MELODIC SENTENCE (THEME) 

The rest 5 basic factors are


2) Chromatic, melodic , harmonic character. Analogy of intervals of 2nds (chromatic) 3rds or 6th (melodic) and 4th or 5th (harmonic ) It is the arpeggio-tail aspect of the melodic theme

3) Chord harmony. Order of appearance of intervals of 3rds which is essentially the harmony of the underlying chord(s)

4) Cycles dynamics. Wave-up, Wave-down dynamics or topology of the melody (structure of "Dolphin words" as termed elsewhere in this book). This includes cadenzas and ascents. 

5) Power of 2 rhythmic expansion. The use of orders of rhythmic speed as powers of 2

6) Instrument or voice timbre. The timbre and nature of the playing instrument (continue sound, string or wind etc)

443. METHOD OF COMPOSITION OF SONGS BASED ON THE 8 BARS BLUES 8BB RHYTHMIC-HARMONIC PATTERN AND MODAL CHROMATIC PAIRS OF CHORDS

 The general  rhythmic harmonic pattern of 12 bars blues denoted by  12BB  CONTAINS THE NEXT 8-BARS BLUES PATTERN

They are in improvisational monotonicity and simplicity between the 1-chord improvisation for meditation and the 12 bars blues improvisations. 

Let X1 X2 X3 be an harmonic triad of chords , in other words consecutive in the wheel by 4ths. They may be major or minor chords then the general 12 bars blues rhythmic-harmonic pattern is the next 



X2X2X2X2
X3X3X2X2
X1X1X2X2

  


THE 8-BARS BLUES PATTERN IS ONLY THE  NEXT WITH 2 CHORD OR 3 CHORDS



X2X2X2X2


X1X1X2X2

Or the 

X2X2X3X3


X1X1X2X2

In the general scheme we might allow for any arrangement of X1 ,X2 X3 on he above squares

If the Xi  X1 X2, X3 AS 3 CHORDS are major denoted by M or minors then we have 8 types of such general 12 bars blues rhythmic-harmonic patterns


MMM

MMm

mMM

MmM

mMm  


If the Xi  , X1 X2  AS TWO ONLY CHORDS are major denoted by M or minors denoted by m then we have 4 types of such general 8 bars blues rhythmic-harmonic patterns.



MM

Mm

mM

mm

Here we do not restrict that X2 has to be in harmonic relation with X1, but it can be also in melodic relation or chromatic relation. 

A usual rhythm is 120 bpm and 2,3, or 4  beats per bar. 

This gives that one such 8BB has duration at most about 8 seconds thus about 6-8 repetitions of this 8BB pattern will give a song a little less or more than 3 minutes duration.

Now the general concept of composing sings based on the 12bB patterns is based on the next

a) We start with a 8BB as unit block and we modulate it or transpose it about 6-9 times

b) We alter the 8BB pattern substituting any of the instances of each of the Xi chords i=1,2 with relative minor or major chords if the X1 X2 is an harmonic pair. And in general with any other diatonic chord if not. 

In the guitar such an improvisation is mostly easy if the guitar is tuned in one of the open overtones tuning. E.g. Open D tuning. 


Also at the meso (=medium) and micro layer, the main 4 factors are 

1) Up, Down or flat vector-waving and is meaning (including which octave) 

2) Density of notes per time unit (many notes theme, very few notes theme)

3) Percentage of harmonic or melodic intervals (acceleration) to the chromatic intervals (deceleration).

4) The poetic micro-meter and poetic macro-meter  in the melodic theme.

In order to create the melody we may proceed as follows.

1)We compose 2 or 3  simplicial sub-melodies one for each part of the song ,  with one note per chord and bar , over the cycle of chords preferably at a chromatic sequence ascending and descending .  In this way we may have more than one note of the simplicial sub-melody per chord but only one per chord and bar. 

If we use keyboards (and this may also be e.g. digital harp in the tablet as in ThumbJam)  , the way to create the melody is the next. For each  lines in the 16 Bar Blocks which is usually a  pair of chords , we layout the chords in the keyboard to see their mutual topology and overlapping. Then we compose 5-6 versions of the melody, by one up or down wave within each chord, which are usually one vector-wave for half or full the chord (123 , or 1234565 or 543 for 3-notes chords or 7654321 for chords with 7nth etc in trochaic poetic meter) . We use balancing structure e.g. if the first is up the next is down and vice verse. But two ups or two downs are for emphasis too. We may split the vector-wave to arpeggio and tail or only arpeggio. We choose the version that we like best and expresses best the emotions we want. We use not one only octave necessarily but 2 or even 3. Starting from high, in high octaves and descending down 1 or 2 octaves is a bird-like melodic approach. If we use harmonica the themes waves for each chord or pair of chords are quite more free. If we use guitar , violin , flute, it is more or less as with the keyboard but again a little more free to follow the constraints and conveniences of the instrument.   

2) We create moves or waves or cycles for each note of the simplicial sub-melody by sequencing during the chord with two types of notes a fast (usually outside the chord) and a slow of double duration on the notes of the chord again ascending or descending with smaller waves. I this way more than 50% of the time of the duration of the melody will be notes of the chord. We may apply the pattern of 4 waves-cycles. Initial idea- variational continuation-contrasting mutation-closure. E.g. Down cycle-down cycle modulated-up cycle-wave shrinking and ending to middle note. Or vice versa Up cycle-Up cycle modulated-Down cycle-wave shrinking and ending to middle note. It is important to realize that such a  wave or cycle need not be 100% over a chord but it can be over a pair of chords as chord-transition theme (x% over one chord y% over the next x%+y%=100%) and sometimes as themes over three chords. Thus each melodic theme of the 4 phases of it may correspond to 4 bars and the 4 melodic themes may rhythmically correspond to the 4 times the 4 bars (2 cycles of 8BB) 

3) We arrange a continuous sound instrument to play the simplicial sub-melody only and a discrete sound (guitar mandolin etc) to play the full waves melody.

Thus

X2X2X2X2

=1st theme

Or 
X3X3X2X2
=1st theme
X1X1X2X2
=Opposition and closure

Or it may be  X2 X2=A theme  X3 X3=B theme X1 X1= C theme
Thus in total

AA or 
BA
and 

CA

We may summarize in short

1) We compose the simplicial sub-melody per bar and chord, which defines the orientation of the waves within a chord.

2) We compose the  poetic measure of the melodic themes (long short notes combinations) 

3) We compose the bridging transition to the next chord

4) We arrange for continuous sound (simplicial sub-melody and bass) and discrete sound instruments. 

For example for Aegean islands (Greece) improvisational folk melodies (mandinades) condylies) with violin or Lyra, the next factors prevail.

1) "Poetic meters" over the same note sometimes notes up to 8 notes. The density of the notes is high. E.g. with 4 notes per  measure-bar and a beat of 80-100 bars per minute gives a tempo of 320-400 beats-notes per minute.

3) Straight vectors ascending or descending usually of 4 or 5 notes so as to reach a new chord neighborhood.

2) Mainly waves by intervals of 2nds (chromatic) inside intervals of 3rds (melodic, either standing or ascending descending, and usually inside a chord  so as to reach the neighborhood of a new chord. The simplistic sub-melody of such a waving melody is essentially an arpeggio of the underlying chord.

An example of such a way of composition is the song of Edith Piaf , la vie en rose.

Examples is music by the trombonist Cesar B

The difference in easiness and familiarity when composing songs based on this method compared to no method, is as the difference of walking by feet compared to moving by a car (the car=8BB pattern)

With the chromatic pairs of chords in the diatonic scale  may get the the names of the modes of the scale too

1M7-2m=IONIAN or Dorian
2m7-3m=DORIAN or Frygian
3m7-4M=FRYGIAN or Lydian
4M7-5M=LYDIAN or Myxolydian
5M7-6m=MYXOLYDIAN or Aeolian
6m7-7d=AEOLIAN or Locrian
7d7-1M=LOCRIAN or Ionian. 

(see also post  364 , 225 and 325  )

Thus the X2=2nd chord of the chromatic pair and X1-first chord of the chromatic pair in its major 7nth form. 

In such a way the 3+4 notes of the two chords make all the 7 notes of the diatonic scale and cover free improvisation over it. 

Here are ideas of a melody morphology. 1st idea  bars 1-2 Repeat 1st idea  bars 3-4 continuation bars 5-6 , closure bars 7-8

This fits also to 15-syllables poetry where each line is 2 parts of the melody 

With the words, syllables 1-4 1st idea repetition syllables 5-8
Continuation syllables 9-12, closure syllables 13-15 




We add here a simple technique to improvise over such 8BB chords patterns  too with the tenor trombone which emphasizes the glissando ability of the trombone..

We must notice that from any note we are in the diatonic scale during a chord there is always a note of the chord at most an interval of 3rd away! 

1) So the method is tho start with an arbitrary note and correct it with the slide by at moist an interval of 3rd to a note that fits the chord

2) When we want to a much higher or lower note during the chord or because the chord changed we just blow harder or softer for a higher or lower overtone (partia) at the same position and then we correct it if necessary with the slide! 

3) The whole process becomes easier if we are on the 3rd octave of overtones where the overtones form the major tonal chord (with a  7nth) . And for thsi the best idea is to utilize a french-horn mouthpiece for the tenor trombone!

If we are capturing the diatonic mode with a pair of chords in chromatic relation (in harmonicas it would be an hexatonic harmonica) then the 8BB pattern will give if we have a theme for a single type of chord.

Ionian-Ionian

Myxolydian-Ionian

or 

Ionian-Lydian

Myxolydian-Ionian

If we want a diatonic model per pair of chords then X2 X3 is a Lydian mode and X1 X2 is an Ionian mode, thus


Lydian 

Ionian


And for hexatonic harmonicas with a chromatic pair of chords  it would be the chords

(3m 4M)= Lydian

(7d 1M)=Ionian

442. METHOD OF COMPOSITION OF SONGS BASED ON THE 12 BARS BLUES 12BB RHYTHMIC-HARMONIC PATTERN


The general  rhythmic harmonic pattern of 12 bars blues denoted by  12BB is the next


Let X1 X2 X3 be an harmonic triad of chords , in other words consecutive in the wheel by 4ths. They may be major or minor chords then the general 12 bars blues rhythmic-harmonic pattern is the next 



X2X2X2X2

If the Xi  X1 X23 are major denoted by M or minors then we have 8 types of such general 12 bars blues rhythmic-harmonic patterns


MMM

A usual rhythm is 120 bpm and 4 beats per bar. This gives that one such 12BB has duration about 24 seconds thus about 6-8 repetitions of this 12BB pattern will give a song a little less or more than 3 minutes duration.

Now the general concept of composing sings based on the 12bB patterns is based on the next

a) We start with a 12BB as unit block and we modulate it or transpose it about 6 times

b) We alter the 12BB pattern substituting any of the instances of each of the Xi chords i=1,2,3 with relative minor or major chords.


The difference in easiness and familiarity when composing songs based on thsi method compared to no method, is as the difference of walking by feet compared to moving by a car (the car=12BB pattern)

In the guitar such an improvisation is mostly easy if the guitar is tuned in one of the open overtones tuning. E.g. Open D tuning. 

Also at the meso (=medium) and micro layer, the main 4 factors are 

1) Up, Down or flat vector-waving and is meaning (including which octave) 

2) Density of notes per time unit (many notes theme, very few notes theme). This is relevant to  if the melody is close to layer 1 , 2, or 3 of a melody .

3) Percentage of harmonic or melodic intervals (acceleration) to the chromatic intervals (deceleration).

4) The poetic micro-meter and poetic macro-meter  in the melodic theme.

In order to create the melody we may proceed as follows.

1)We compose 2 or 3  simplicial sub-melodies one for each part of the song ,  with one note per chord and bar , over the cycle of chords preferably at a chromatic sequence ascending and descending .  In this way we may have more than one note of the simplicial sub-melody per chord but only one per chord and bar. 

If we use keyboards (and this may also be e.g. digital harp in the tablet as in ThumbJam)  , the way to create the melody is the next. For each  lines in the 16 Bar Blocks which is usually a  pair of chords , we layout the chords in the keyboard to see their mutual topology and overlapping. Then we compose 5-6 versions of the melody, by one up or down wave within each chord, which are usually one vector-wave for half or full the chord (123 , or 1234565 or 543 for 3-notes chords or 7654321 for chords with 7nth etc in trochaic poetic meter) . We use balancing structure e.g. if the first is up the next is down and vice verse. But two ups or two downs are for emphasis too. We may split the vector-wave to arpeggio and tail or only arpeggio. We choose the version that we like best and expresses best the emotions we want. We use not one only octave necessarily but 2 or even 3. Starting from high, in high octaves and descending down 1 or 2 octaves is a bird-like melodic approach. If we use harmonica the themes waves for each chord or pair of chords are quite more free. If we use guitar , violin , flute, it is more or less as with the keyboard but again a little more free to follow the constraints and conveniences of the instrument.   

2) We create moves or waves or cycles for each note of the simplicial sub-melody by sequencing during the chord with two types of notes a fast (usually outside the chord) and a slow of double duration on the notes of the chord again ascending or descending with smaller waves. I this way more than 50% of the time of the duration of the melody will be notes of the chord. .We may apply the pattern of 4 waves-cycles. Initial idea-variational continuation-contrasting mutation-closure. Or only3 phases  Initial idea=position , Contrasting idea =opposition , and finally closure  E.g. Down cycle-down cycle modulated-up cycle-wave shrinking and ending to middle note. Or vice versa Up cycle-Up cycle modulated-Down cycle-wave shrinking and ending to middle note. It is important to realize that such a  wave or cycle need not be 100% over a chord but it can be over a pair of chords as chord-transition theme (x% over one chord y% over the next x%+y%=100%) and sometimes as themes over three chords. Thus each melodic theme of the 3 phases of it may correspond to 4 bars and the 3 melodic themes may rhythmically correspond to the 3 times the 4 bars (1 cycles of 12BB), Thus  

X2X2X2X2
=1st theme
X3X3X2X2
=opposition
X1X1X2X2
=closure

Or it may be  X2 X2=A theme  X3 X3=B theme X1 X1= C theme
Thus in total

AA
BA
CA

3) We arrange a continuous sound instrument to play the simplicial sub-melody only and a discrete sound (guitar mandolin etc) to play the full waves melody.


We may summarize in short

1) We compose the simplicial sub-melody per bar and chord, which defines the orientation of the waves within a chord.

2) We compose the  poetic measure of the melodic themes (long short notes combinations) 

3) We compose the bridging transition to the next chord

4) We arrange for continuous sound (simplicial sub-melody and bass) and discrete sound instruments. 

For example for Aegean islands (Greece) improvisational folk melodies (mandinades) condylies) with violin or Lyra, the next factors prevail.

1) "Poetic meters" over the same note sometimes notes up to 8 notes. The density of the notes is high. E.g. with 4 notes per  measure-bar and a beat of 80-100 bars per minute gives a tempo of 320-400 beats-notes per minute.

 CHROMATIC TONALITY AND ALL 7 MODES MODULATIONS OVER THE  RHYTMIC AND HARMONIC PATTERN  OF 12-BARS BLUES.


In the blues (that may be somehow considered a type of rapsody concept collective composition and improvisation) the rhythm is  also standardized to e.g. 12-bars blues, which corelated the rhyrhmic measures with the sequence and duration of the 3 chords 1M, 4M 5M or  1M 2m 5M.

And we may subtitute 

5M with 3m or  7d

But more generally in chromatic tonality we may substitute one of the basic 3chords with some ofthe chords of the chromatic tonality thus we may substitute


1M  with 3M or 6M (besides 3m, 6m)

4M with 2M or 6 M (Besides 2m, 6m)

5M with 3M or 7M. (besides, 3m, 7d) 

e.g. 

1M1M1M1M
2m2M6M6M
3M5M1M1M


When making the substititutionw it is good to keep the rule of the previous article, that is

 60% harmonic chord transitions, 30% melodic transitions, 10% superchromatic transitions. 

As alternative methods we have that the chord progression of the 12 bars blues can be shifted to all the 7 modes ofthe diatonic scale, so that it can produce different tonal or chrmatic tonal 12-bars blues 


Here are all the 7 modes of the chord progression for the 12 bars blues

IONIAN                  1M 4M 1M 5M 1M 
DORIAN                 2m 5M 2m 6m 2m
FRYFIAN                3m 6m 3m 7d 3m
LYDIAN                  4M 7bM 4M 1M 4M  (chromatic tonality because of the 7b)
MIXOLYDIAN        5M 1M 5M 2m 5M
AEOLIAN                6m 2m 6m 3m 6m
LOCRIAN                7d 3m 7d 4#M 7d  (chromatic tonality because of the 4#)

If we are capturing the diatonic mode with a pair of chords in chromatic relation (in harmonicas it would be an hexatonic harmonica) then the 12BB pattern will give if we have a theme for a single type of chord.

Ionian-Ionian

Lydian-Ionian

Myxolydian-Ionian

If we want a diatonic model per pair of chords then X2 X3 is a Lydian mode and X1 X2 is an Ionian mode, thus

Ionian 

Lydian 

Ionian

Or 

Lydian 

Lydian 

Ionian

And for hexatonic harmonicas with a chromatic pair of chords  it would be the chords

(3m 4M)= Lydian

(3m 4M)=Lydian

(7d 1M)=Ionian 


A JOY-BASED PATTERN TO COMPOSE SONGS INSPIRED FROM THE EARLY NEW ORLEANS  BLUES JAZZ SONGS.

 See also post 430, 322, 426, 216. 215, 205

We remind also that the simplest and most effective way to compose songs (the music without  the words) is starting from the simplest and proceeding with the more complicated. Thus the order is

A) First the rhythm and morphological parts of the song

B) Then the harmony with the chord progression

C) Last the simplicial melody and the full melodic themes for each chord or chord transition of the chord progression (possibly with tail and arpeggio parts). 

The idea for this structure in composing soengs is from the new Orleans jazz songs. 


The joy of the composition of such songs is not only on he next below 

a) system of joyful  harmony and chord progression creation but also

 b) on the joy of the rhythm rhythm which is at least 180 bpm . Furthermore we may use fast notes double the main tempo for reasons of joy.  

c) joy from the melodic waving so that  if we label + and up-move in a waving and by - an equal time and interval down move of the waving the total waving score of the melody is plus. In simpler terms we may have melodic themes as waves that are by 2nds and start and end a 3rd lower or higher (higher is more joyful) thus withing a chord. Furthermore we may use fast notes double the main tempo for reasons of joy. Then chord changes are modulations of the melodic theme. 

Joy from the harmony: 

A1) The center of the songs is a joyful triplet of major chords in harmonic relation, in other words the

classical 5M, 1M , 4M. It is set in a sequence that corresponds to a rhythmic pattern. E.g. 

(1M, 4M, 1M 5M7)   with equal duration per chord. Thus a 4-fold rhythm. 

Usually, because the triplet of major chords has two harmonic relations (5M-1M) and (1M-4M) the rhythmic  pattern is divided in 2 , each part corresponding to one of the two harmonic relations. 

Simplistic counter-melody soloing could be on the 7-1-2 triad notes around the 1st semitone of the diatonic scale (1-2-1-7-1) or on the 2-3-4 triad notes around the 2nd semitone of the diatonic scale (3-4-3-2-3)

Or alternatively a 3-fold rhythm as follows  (1M, 4M, 1M, 5M7 , 1M) where the first 2 chords and the last chord have  double duration the time compared to the 3rd and 4th. So in rhythmic units it is (2, 2 1,1,2).

This initial harmonic and rhythmic center of the songs is repeated two times (at least) and corresponds to a joyful refrain, from which nevertheless the songs starts returns and ends.

Each time that we return to the central chord progression, it is not necessary to return with the same melodic theme. It can be different. 


A2) Then after each (1M, 4M, 1M, 5M7 , 1M) repeated twice we interpolate a less joyful rhythmically isomorphic pattern, derived with one of the 5 systems of substitutions of the major chords of the central part. (X1, X2, X3, X4 , X5) This may be called the couples of the song and have duration at least half of the duration of the central part, so as to guarantee that the joyful part has more duration than the possibly sad part. 

The system of substitutions are the next 5, which preserve the harmonic relations of the initial central chord progression. The substitutions are based on melodic (relative chords ,2 common notes) relations of the chords. That is why the 2m can also be substituted with 7bM and the 7d with the 2m, while the 7M7 with the 2#m and 5#m. 


Primary a, b substitutions

                                                      5M   1M   4M

substituted with                             3m    6m   2m (which 2m can again be substituted with 7bM)

or with                                          3M7   6M7 2M7


Primary c, d substitutions

                                                      5M   1M   4M

substituted with                             7d    3m   6m

or with                                          7M7   3M7 6M7


Secondary a, substitutions

                                                      5M   1M   4M

substituted with                             5m    1m   1m


A most intersecting is the double substitution e.g.  1M with (3M7 6m) with teh same duration

or  5M with (7M7, 3m)  or 4M with (6M7, 2m)  .


And also the transformation of the harmonic relation to chromatic with the substitution

of 5M7 resolving to 1M with  7m shifting to  1M or 1m

Of  1M resolving to 4M with   3m shifting to 4M or 2m.


We may extend the major harmonic triplet to a major harmonic 5 cycle as follows

in the 5M7 1M7 4M , if the 1M->4M is substituted by  6M7 -> 2M7 we resutlt in a 5 harmonic cycle 6M7-2M7 5M7 1M 4M

In general we have a Universal adequacy of the substitutions in the sense that if we have a melodic  theme within a chord and we want to have a

 a) harmonic (by 4ths or 5ths) modulation of it 

b) melodic (by 3rds) modulation of it 

c) Chromatic (by 2nds) modulation of it 

it is always possible with the above melodic substitutions of the chords. 

These substitutions introduce, blue notes outside the diatonic scale, that are included in the chords, and may define harmonic minor scales, double harmonic minor scales, blues scale etc. 

The preference order o introducing blue notes is the next


 Diatonic scales in harmonic relation with the focus diatonic scale

1.  7b                  (5m)

2. 4#                 (7M7, 2M7)

harmonic or double harmonic minors

3. 5#                (3M7, 4m)

4. 1#               (6M7)

Neapolitan , double harmonic minor) 

5.  2#   (7m7, 1m) 



So the chord progression of the whole song is a sequence of pairs of pieces as follows


(1M, 4M, 1M, 5M7 , 1M)

 (X1, X2, X3, X4 , X5)

The first corresponds to joy and lasts twice as the second which corresponds to degrees of sadness.


The joy of the composition of such songs is not only on he previous 

a) system of harmony and chord progression creation but also b) on the rhythm which is at least 180 bpm and 

c) melodic waving so that  if we label + and up-move in a waving and by - an equal time and interval down move of the waving the total waving score of the melody is plus 


Here are ideas of a melody morphology. 1st idea (1st 2 bars) Repeat 1st idea ( bars 3 and 4) continuation, (bars 5,6,7,8) closure (9,10,11,12)




We add here a simple technique to improvise over such 8BB chords patterns  too with the tenor trombone which emphasizes the glissando ability of the trombone..

We must notice that from any note we are in the diatonic scale during a chord there is always a note of the chord at most an interval of 3rd away! 

1) So the method is tho start with an arbitrary note and correct it with the slide by at moist an interval of 3rd to a note that fits the chord

2) When we want to a much higher or lower note during the chord or because the chord changed we just blow harder or softer for a higher or lower overtone (partia) at the same position and then we correct it if necessary with the slide! 

3) The whole process becomes easier if we are on the 3rd octave of overtones where the overtones form the major tonal chord (with a  7nth) . And for thsi the best idea is to utilize a french-horn mouthpiece for the tenor trombone!

The next video is a well known experiment with many interpretations.
In our case of musical composition we interpret it that the big balls or rocks are the simple but macroscopic factors of a musical piece that should come first . Here are
1) The rhythm and parts of the song (8, or 12 or 16 or 32 bars blocks)
then the
2) the chords
3) simplistic sub-melody or bass
4) The melody etc.
