From my point of view, I have experienced 3 basically different types of improvisation and I am aware of a 4th modern type of improvisation i digital music
A) Improvisation of single instrument unacompanied by a single person (UNPREDICTABLE RHYTHM, HARMONY, UNPREDICTABLE MELODY).
A very convenient and instructive instrument to do such improvisations is the Muzix pro (https://www.youtube.com/watch?v=qfvHNmO1GoQ&t=26s ) with the diatonic Isomorphic 2-dimensional layout by alternating 3rds, at the diatonic scale C major . See post 312.
The basic idea here is to chose a source od simplicity and invarious degrees in time more complexity and returning to the simplicity. Thus SIMPLICITY->COMPLEXITY->SIMPLICITY , ETC and also by REPETITION , ASSIMILATION, INNOVATION . THE MAIN CONCEPTIS TO CREATE A "FLOW" AND REMAIN INTHE "FOW" A TERM OF PSYCHOLOGY THAT DESCRIBES THE FLOW OF ENERGY AND CREATIVE FORCE FROM THE IMMORTAL SOUL TO THE MORTAL PERSONALITY . The improvisation with such a melodic percusion instrument like a handpan or tongue drum (which is much like a metallophone) is the 1st type of improvisation (single instrument and unpredictable rhythm, unpredictable harmony, unpredictable melody )
We should not forget of course the 3 principles of improvisation as the post 295,
BASIC PRINCIPLE 1=HARMONY POLARITY
BASIC PRINCIPLE 2: MELODIC MONOTONICITY-VARIATION POLARITY
BASIC PRINCIPLE 2: THE BIOWARE OVER THE HARDWARE.
For analysis of these 3 principles see below,
THE 4 SOURCES OF SIMPLICITY ARE
1) RHYTHM (GROOVE) (We keep the rhythm invariant and we shift it over the musical notes and octaves)
2) ASCENDING-DESCENDING-STAYING SHAPE OF A MELODIC THEME (We keep the melodic theme shape invariant and we translate in the scale , or invert it or elongate it)
3) A BASS LOOP THAT REPEATS (We keep a bass loop invariant and we enhance it with melodic themes)
4) ONE OR TWO CHORDS ALTERNATION (We keep the harmony of the 1or 2 chords invariant and we create parallel fitting melodic themes)
Here is a video by a nice girl and improviser who explains these 4 sources of simplicity
https://www.youtube.com/watch?v=PEuwaKR0cbY&ab_channel=AmyNaylor
B) The Rapsody method of improvisation , based on a simple cycle of chords and parts of the melody (PREDETERMINED HARMONY AND RHYTHM , UNPREDICTABLE MELODY).
We may as well put settings to play the chords to the digital instrument TOUCHSCAPER https://www.touchscaper.com/ which is a marvelous and very customizable musical instrument in the ipad. It supperts easily chord progressions and arpeggios either strict or randmized that are alo not only on pitch and timr but also one sound-color ranging between two sounds or instruments. It supports also drum patterns that may change with the chords and sessions organization whichcombines both automated playing and interactuve playing. It can also communicate well with other sound machines for other types of sounds and recording.
This is best done by listening with one earphone at one ear the song and whistling the countermelodies utilizing the 2nd ear to control the result of the whistling.
Depending on the musician the difficulty is varying. In my case, I excercize the A-type 60% of my time the B-type 25% of my time and the C-type the 15% of my time. But I consider the order of dificulty as C>>A>>B.
We summarize for the three cases A) B) C) a more detailed analysis
For the method A) Improvisation of single instrument unacompanied by a single person.
we summarize some of the maon idaes that I use.
My personal approach to similar type of improvisation is as follows
HARDWARE IDEAS
1) INSTRUMENT I utilize a 4-strings instrument instead of 3-stringsm although sometimes a 3-strings too. Of course I may use a 6-string instrument.
2) STARTING SCALE I chose a basic scale, usually the natural defoult scale of the instruent which is marked on its fretboard.
3) The TUNINGS are preferably overtones cuatro tunings thus cavaco cuatro or Swedish troll fiddle tuning. But I can also use the venezuala cuatro or ukulele (guitar tuning of 4 highest strings)
CHORD-BASED IDEAS:
BASIC PRINCIPLE 1=HARMONY POLARITY : HERE WE PLAY WITH OUR FEELINGS OF HARMONY AND THE POLARITY BETWEEN BEING INSIDE THE HARMONY OF THE UNDERLYING CHORD AND OUTSIDE IT. WE ENHANCE THIS PRINCIPLE WITH THE OVERTONES ARPEGGIO PATH FOR OVERTONES INSTRUMENTS OR OVERTONES TUNINGS. THIS STATES THAT WHEN YOU ARE IN A NOTE AND YOU ARE WANDERING OF HOW MUCH OUTSIDETHE THE UNDERLYING CHORD AND WHERE TO GO, THEN THE THE FRIENDLY CHARMING PATH TO FOLLOW IS TO ASCEND OR DESCEND FROM THIS NOTE ACROSS THE OVERTONES OF THE INSTRUMENT WHICH ESSENTIALLY ARE A MAJOR CHORD (IN THE BRASS INSTRUMENT BY BLOWING LESS OR MORE) AND WHEN YOU REACH A NOTE EITHER STAY IN IT IF IT IS SUITABLE OR SHIFT TO A CLOSEST ONE WHICH IS SUITABLE. IN THE STRING INSTRUMENTS THAT ARE NOT IN OVERTONES TUNING THIS FRIENDLY CHARMING PATH IS NOT AN OVERTONES SEQUENCE BUT A CHROMATI SEQUENCE OF MINOR 2NDS (SEMITONES).
4) CHROMATIC TONALITY
Although I chose a diatonic scale, that is from 7 notes I involve also some or all of the 5 blue notes that result to all 12-notes of the musical universe. This is usually done in chords by convrting major to minor and vice versa E.g. a stanard chromatic extension of the chords of the diatonic scale is 3M instead of 3m and 7M instead of 7d. But also the minors 6m can become 6M when resolving to 2m and also the 3m to 3M when resolving to 6m, and the 2m to 2M7 when resolving to 5M. In addition we mau suround each major chord with two dimisnsihed chords an interval of 2nd away, that resolve to them, in the same way that the 7dimished resolves to 1M.
For the next steps I will enlarge more in the subsequents paragraphs
5) I improvise on major-minor lternations of HARMONIC CYCLES
with bridging the chords small melodic themes too.
6) I improvise on major-minor lternations of CHROMATIC CYCLES (like Andaluzian cycle)
with bridging the chords small melodic themes too.
7) I improvise on ISOMORPHIC CYCLES OF CHORDS (X1-X2-X3etc) with (Y1-Y2-Y3 etc) Most often of chromatic sequences that are melodic or harmonic isomorphic . I bridge them with small melodic themes too.
8) 2-VOICES AMBIGUITY REVEALED
I ascend or descend a mode of the scale with 2-voices simulteneous notes intervals of 3rds. The ambiguity of them is that they can be part of a minor or dimished chord (sad feeling) or a major chord (happy feeling). So 1st I play the 2-voice interval andthen I reveal it as major ot minor chord depending on the mood and to if I am ascending or descending.
MELODIC THEMES BASED IDEAS
BASIC PRINCIPLE 2: MELODIC MONOTONICITY-VARIATION POLARITY . HERE WE PLAY WITH OUR FEELINGS OF MONOTONY AND VARIATION AND THE POLARITY BETWEEN BEING MONOTONOUS BY REPEATING A MELODIC THEME AND BEING INNOVATIVE IN CREATING TRANSLATIONS, INVERSIONS AND MUTATIONS OF IT.
9) SMALL MELODIC THEMES VARIATIONS
The idea here is to start with short and rythmic melodic themes and apply the 3 basic variations , like translation (chromatic, melodic, harmonic) inversions and muttaions.
MIXED CHORD AND MELODIC THEMES IDEAS
10) "WALKING THROUGH PARTS OF A TOWN", FLUID-CHORD-TRIADS or 2-VOICE ACCOMPANYING OF MELODY.
This idea is very old idea in ancient folk music before the era of classical music when complicated melodies where accompanied by power chords that are essentially 2-voices chords. It is an idea also similar to the previous at 10) except that instead of alternating standard 3-voices chords with melodic themes, we are struming or arpeggiating on a single triad which is not standard major or minor and so that it is constantly changing at each note of the melodic themes so that the 2 lower notes are rather stable and are used as 2-voice chord which accomnies the 3rd note which is changing faster and is usually the higher. Here is included also the accomnaying of the melody of the software arpeggiator ofthe sofware MIDI GUITAR 2.
11) "TRAVELING AMONG AND WITHIN TOWNS"
This is a generic type of improvisation where I improvise "randomnly" with melodic themes that are translated , inverted and mutated mainly within the diatonic scale, but at their standing notes (melodic centers) I apply arpegiation or struming of the close local major or minor/diminishd chord which fits to the melody at that time. The choices are only 2-3 at each time. Here the metaphor for the melodic themes is traveling and the metaphor for chords is "town"
This applies especially well in overtones tunings and of course on the full 6-string 1st overtones tuning. I improvise horizontally with melodies and at the standing note I cross-over vertically at the local overtones "gate" which is of course an extended overtones arpeggio of a local major or minor chord.
For t he case of B) The Rapsody method of improvisation , based on a simple cycle of chords and parts of the melody
(see e.g.post 294)
BASIC PRINCIPLE 2: THE BIOWARE OVER THE HARDWARE. HERE WE GIVE PRIORITY TO THE ACQUIRED PSYCHOLOGY AFTER LISTENING MANY MELODIES OF OUR PERCEPTION OF MUSIC MELODY OVER HABITS OF PLAYING THE INSTRUMENTS OR OF THEORETICAL PRECONCEPTION IN THE MUSICAL ONTOLOGY: WE SPENT 5 ONLY MINUTES A DAY TO SING A MELODY THAT WE LIKE (KNOWN OR NEW) AND THEN PLAY IT AS IMPROVISATION ON OUR INSTRUMENT (see also post 288 ).
we summarize
Other cultures with similar practice is the Irish and Celtic reels, the fado music and tradition of Blues.
By insisting playing all chords on the same inversion in string instruments with fretboard (at best in normal forms which is easy in overtone tunings) the chords of diatonic scale are spread across the fretboard. This may require larger moves of the hand, but it offers voices of the chords at different pitch ranges which is more rich at the final musical result. This is amore pianno-like or harp-like positioning of the chords on the fretboard as the relative pirches of their roots are easily and intuitively visible. Thus instead of playing the chords only as open at the first few frets we play them as only 3 or 4 consecutive strings shapes across all the fretboard.
2) THE SARTING SIMPLICITY, RHYTHM AND HARMONY: THE POETIC MEASURE RHYTHM OF THE CHORD PROGRESSION
Musical porphology: The chord-progression.
Or if A=1M the first chord and B=5M7 the second it is a pattern of 4 bars (and also musical score measures)
AABA where each step A or B is of 50-60 bps.
A | A | A | A |
B | B | A | A |
The patternof chord-distribution in measures that comes from the poetical measure (it suggest 3 repetitions A and one resolving devation B) ismet not only Greek Cretan Rapsody improvisation music, but also in Irish music and Swedish and Scandinavian folk music with fiddle.
1M | 1M | 1M | 1M |
5M7 | 5M7 | 1M | 1M |
|
Inother cultures we find the "Couple" part of the chord progression which may have different lyrics when repeating and the "Refrain" part of the chord progression (which is the peak of the song) which has always the same lyrics. The refrain part is what one usually remembers from the song, and usually inspires the title ofthe song.
Other patterns of distrubution of 1,2,3,or 4 chords over musical measures can be used, but the idea is that they must be simple , and played repetitively in cycle so that those that improvise the melody can rely on it and create complexity over this simplicity with the layered structure of a melody (simplicial submelody and full melody)
It supposed that the singing melody might have 15 notes in the 2 poetic lines, but by extending syllables, very often it may have less notes. Neverthless the emotion is mainly created by the simplicial submelody of the singing melody which is only 2 notes per poetic line thus in total 4 notes (and measures in the musical score) whch make the macro-melodic theme.
In the Sweedish folk music there is very often the upper cyclic pattern of (simplicial submelody) notes and macro-scale melodic theme of middle-scale melodic themes (see below) parallel to the chord rhythmic pattern A A B A, notes a1 a2 a3 a1 , with pitch order a1<a2<a3>a1.
But we can conceive it as 4 parts , 3+1 too: If we divide the 15 steps into parts by 4 steps, it is 3 parts of 4 steps (that can also be 3 repetions of a melodic pattern ) and one concluding part of 3 steps. This can be also a patern on the steps of the correlated dancing. The correlation of the harmony with the poetic measure may vary but a very usual way is E.g. for the pair of chords 1M-5M7 (or 6m-3M7) that the first chord is at the 1st 2nd and last 4th parts from the 4 and the 2nd 7nth chord at the 3rd part. So it is 1M-1M-5M7-1M (or 6m-6m-3M7-6m ). Or it can be 1M-1M-1M-(5M7/1M) (or 6m-6m-6m-(3M7/6m) )This is a common pattern both for Celtic folk songs but for Greek , Cretan mantinades. This correlation is different of course for the 12-bars blues where the chords is a different triad and the poetic measure different.
It is supposed that it is the wordless but poetic musical speaking of the feelings. This instrumental embelishment counter melodies is dense in the number of notes more complicated than the human singing voice, and is in between and during the silent time intervals of the human voice singing melody. The fact that it is more complicated is because it corresponds usually to the dancing steps of the dancers, which is double, or 4 times (or even 8 times) faster that the tempo of the syllables of the lyrics.
If in the performed improvisation is only instrumental, then this will lead to an alternation of two speeds of improvisational melodies within the same chord-cycle and poetic measure a) The "singling" improvisatinal melody and b) the "dancing" improvisational melody which is 2 or 4 times faster than the "singing". They should be played preferably by different musical instruments e,g. a wind and a string instruments respectivlly or a bowed instrument and a plucked string instruent respectively.
The rhythm-frequency of each poetic-half line and musical score measure is about 50-60 beats per minute (the beats of a calm heart) . Thus the beats per minute of each poetic sylalble is supposed to be 4-times so thus 200-240 bpm. While the fast dancing melody where each measure and half line has 8-notes would be 400-480 bpm
longitudinal chords)
micro or macro-chromatic and melodic , harmonic.
1) oscillations around a note of the chord. (micro-chromatic) E.g. if 1 is the note and 0note not inthe chord , then patterns like 1-1-0 (70% in the chord) or 1-0-1-0 (50% in the chord)
2) Up-down wavings-arpeggios within the scale-chromatic closure of the chord
(macro-chromatic) (or vector-chord) E.g if c-e-g is the chord then c-d-e-f-g-f-e-d-c (60% in the chord). The chromatic closure of the chord is within the diatonic scale, but it may be with blue or chromatic notes so instead of natural mnor it may have harmonic or double harmonic minors. Sometimes with still different blue notes like 5#, or 1# or 4# or 7b.
Pure-chord arpeggios (melodic or harmonic) . e.g. if if c-e-g is the chord then e.g. c-e-g-e-c etc (100% in the chord)
The pure-chord arpeggios are mainl of two types
3)the melodic from intervals of 3rds (e.g. c-e-g-e-c)
4) The harmonic that are arpeggios of the included power chord e.g. c-g-c'-g-c
The middle-scale melodic theme is part of an "arpeggio" of the (chromatic) closure of the chord (or vector-chord), as contrasted to the (simplicial) macro-melodic theme , which is usually more or less an exact arpeggio of the accompanying chord.
In the Sweedish folk music there is very often the upper cyclic pattern of (simplicial submelody) notes and macro-scale melodic theme of middle-scale melodic themes (see below) parallel to the chord rhythmic pattern A A B A, notes a1 a2 a3 a1 , with pitch order a1<a2<a3>a1.
The micro-melodic themes are mainly chromatic (intervals of 2nd) , but in Irish folk reels they may be also from intervals of 3rds, 4ths/5ths. The middle-melodic themes mainly melodic (intervalss of 3rds) , and the macro-melodic theme of the simplicial submelody mainly harmonic (intervals of 4th , 5th or octave). Theya re conceived as themes of the simplicial submelody .
THE EMOTIONAL AFFECTION CENTER THAT TRADITIONALLY IS AT THE ACCOMPANYING CHORD, CORRESPONDS ALSO AT THE MODE-LONGITUDINAL CHORD (SEE PSOT 296) AND THEREFORE ALSO AT EACH NOTE OF THE MACRO-SCALE MELODIC THEME (WHICH AS WE SEE CORRESPONDS AND EXPANDS ALSO TO THE MIDDLE-SCALE MELODIC THEME). THUS USUSALLY AT 60 bpm WHICH IS USUALLY THE RHYTHM OF A CALM HEART.
THE DANCING-KINETIC AFFECTION IS FOUND AT THE MIDDLE-SCALE AND MICRO-SCALE MELODIC THEMES. THEREFORE AT 240-480 bpm
Once someone has mastered the ability in a fluent way to improvise easily over a chord cycle of 2 or 3 or 4 chords, then he gradually can extend the ability toimprovise over larger cycles of chords and chord progressions,which means a rich ability of composing songs starting with improvasations.
For the case of C) The simplicial counter-melody improvisation parallel to an existing song.
(see e.g. post 289 )
we summarize
The ability of this is after we have mastered improvisation as in post 288.
See also posts 118, 128, 197, 183, 102, which contain more ideas.
That is why when turning the singing improvisation to a melody of a musical instrument, it is more convenient to do so with, an harp, or a panflute, or an harmonica , then in general a diatonic instrument etc.
A practice that would implement the above in easier way is
(See also post 271 about learning many instruments simulteneously utilizing simplicial submelody improvisation system and post 275 about whistling)
1) Download the song as an mp3 file , then open it in Audacity, and utilize its function of finding the chords.
2) We look at the chord progression and try to identify the main diatonic scale , from which it may deviate chtomatically.
3) Then we choose the appropriate instrument that may diatonic at this scale or even chromatic. It may be a wind instrument like harmonica, flute, clariphone sax etc or it may be a bowed instrument like violin , metric-lyra celo-lyra (see post 264) or other stings instruments like cuatro, guitar, bouzouki, mandolin, mandola, etc.
4) At first we whistle the simplicial counter-melody while the song is playing.
5)We may also record the whistling in the computer, while we listen in one only earphone and in one ear, the parallel song from the mobile or another computer. This may create an entereily new song and new melody and even different chord progression inspired and stimulated by the initial parallel song. That is why a more likable way of the whistling melody should not be considred as a "mistake" but as a more likable melody of a new song, inspired from the initial.
6) Then we repeat the whistling simplicial counter-melody with the chosen instrument
7) If we are multi-intrument player, we rotate the instruments from the easiest to the more demanding (e.g. harmonica, then celtic harp, then chinese panflute, then marked scale cuatro, then fretted-lyra , then straight flute, then clariphone or sax etc) playing similar simplicial counter-melodies for this song. If we do that we try to identify ourself the with the simplicial counter-melody and consider that we actually we laer a simplicial counter-melody for thsi song rtaher than that we learn the particular instrument that we play). See also post 271.
A METHOD TO CREATE THEORETICALLY BUT ALSO PRACTICALLY SIMPLICIAL COUNTER-MELODIES:
Such chord-bridging melodic lines use a last small part of the previous chord duration and a small initial part of the new chord duration. During the rest ofthe time there is strumming of the chord or a achord arpeggio or variations of small melodic themes inside the chord by intervals of 3rd or 4th/5th. Thus melodic-harmonic variaonions. While when bridging two succesive chords there may be melodic themes variations by intervals of 2nd 3rd or 4th/5th (thus chromatic-melodic-harmonic).
This technique utilizes the simplicity of the information of the set of chord and translates it it to a simple information about the partition of the types of variations of simple melodic themes with the time placement and duration of the chords.
With this technique we may create simplicial counter-melodies parallel to melody.
