We have described in post 9, 63, 65 how chord-transition melodic moves can be composed.
1) Chromatic simplicial sub-melody. A second a but more sophisticated way is to do exactly the same except that the 1st voice is defined not by the highest note in the chords but through the simplicial submelody. The simplicual submelody is defined by the next rules.
1.1) When two successive chords of the chord progression have notes that are one semitone distance only, we chose these two notes as notes of the simplicial sub-melody. For reasons of flexibility we allow two notes per chord if necessary. This happens for all cases that the two consecutive chords in a diatonic scale that are at roots distance of an interval of pure 4th (5 semitones) or pure 5th (7 semitones) or if they are mutually complementary chords (with roots of one step of the scale apart). In general it is a good idea to chose as notes of the simplicial submelody for two successive chords in the chord progression, two notes, one from each chord with the minimum distance in semitones from the notes of the two chords. And alternatively for a 2nd voice we may take the 2 notes in the chords respectively with the maximum distance between them for maximum action of waving movements! This in general may lead to two notes per chord in the chord progression, the second note is reserved for the 2nd voice etc. The more correct rule to find the simplicial submelody is as few notes per chord as possible that give the basic feeling of the melody.
1.2) If the two consecutive chords are mutually relative with two common notes, the notes of the simplicial submelody for each chord are either a common note or the note that the other chord does not contain!
1.3) Chromatic links simplicial submelody (also bass lines) In general we may have the next rule. If X1, X2 are two succesive chords of the chord progression, and we are at X1, a chromatic ling or chromatic bridge is defined by finding two notes a1 in X1, a2 in X2, so taht a1-a2 is at the minimum interval distance among all other chord notes. Then the chromatic link starts with a1, b1,b2....,bn,a2 , and with a2 and all the intermediate steps are one semitone distance.

Then the chromatic link starts with a1, b1,b2....,bn,a2 , and with a2 and all the intermediate steps are one semitone distance.
The previous rules of minimum distance notes and disjoint notes of relative chords for two consecutive chords of the chord progression, determine at least one simplicial sub-melody for each chord progression! We may allow two notes per chord for reasons of flexibility. Then we extend as in 1) the simplicial submelody to the full melody where the original simplicial submelody are centers of the full melody. This means notes that sound more time than the other notes. The rules of the simplicial sub-melody give a more passionate melody with conflicts and resolutions according to the chord progression. After we defined fine the notes of the simplicial sub-melody, then we create the full melody by composing bridges between its notes , with other sizes of intervals.
1.2.1) Minimal chromatic drone sub-melody (MCD sub-melody).
This simplicial sub-melody is like the chromatic sub-melody, except that we utilize preferably the common notes of the chords, and we require it
1.2.2) of as few notes as possible and
1..2.3) of as little distance as possible.
The rules are the next
Rule 1: We start from the chord and we find a common note with its next chord. If there are two common notes, we look at the next 3rd chord and chose this that is also either a note of the 3rd--next chord or minimal distance of a note of it. We proceed in this way till the last chord of the underlying chord progression.
It can be proved that if the chord progression are chords of a diatonic scale, then the minimal chromatic drone melody, can have only some or all of the first 3 notes of the scale (e.g. in a C major mode diatonic scale the c, d, e)
A minimal chromatic drone sub-melody need not be a kind of bass-line! It very well be a kind of very high register or octave simple melodic line. Personally I prefer the latter.

2) Harmonic simplicial sub-melody. Probably best method of creating first the simplicial sub-melody is based on preferring intervals distances of the notes of the simplicial sub-melody (opposite to the previous method) that are large intervals ,namely intervals of 5ths , 4th 6th or 8th. . The simplicial sub-melody is somehow the centers OR OSCILLATION BOUNDARIES, of the final melody (e. g. Chord-Court melody see post 92) and most often it is one note per chord of the chord progression . It can also be considered as a very simple bass line parallel to the melody. But also bass-lines can be created by the chromatic links or bridges of the chords. So the rule to choose the simplicial sub-melody is the next
3.1) If we have two successive chords X(1) -> X(2) in the chord progression, and a is the note of the simplicial sub-melody belonging to chord X(1) , and b is the not of the simplicial sub-melody belonging to the chord X(2), then a->b is an interval in the following order of preference 5th, 4th, 8th, 6th.
If the X(1) -> X(2) are in a diatonic scale and in the relation of resolution (successive in the wheel by 4ths) e.g. G->C then we have 3 choices for a->b, the g->c, or b->e, or d->g. If the X(1) -> X(2) are in the relation of relative chords (two common notes) e.g. C->Em then we have 2 choices for a->b,
c->g, or e->b. And if the X(1) -> X(2) are in the chromatic or complementary relation of chords (roots that differ by one step of the scale) e.g. C->Dm, then we have one only choice or a->b, here the c->f. After we have defined the simplicial sub-melody then we create bridges between its notes by smaller intervals e.g. 3rds or 2nds. IT IS IMPORTANT TO NOTICE THAT IN A CHORD ITI S NOT ONLY THE ROOT AND DOMINANT THAT CREATE AN INTERVAL OF 5TH, BUT ALSO THE MIDDLE NOTE WITH THE 6TH AND THE 7NTHOF THE CHORD.
3) Default simplicial sub-melody. This is simply the melody created by the roots of the chords of the chord progression.
THE NOTES OFTHE SIMPLICIAL SUBMELODY ARE NOT MOST OFTEN INDICATING THE CHORDS OF THE ACCOMPANYING CHORD PROGRESSION BUT ALSO ARE CENTERS OFTHE MIDDLE-SCALE MELODIC THEMES. WHILE THE NOTES OF THE SIMPLICIAL SUBMELODY MEY DEFINE A (SIMPLICIAL) MACRO-SCALE MELODIC THEME.
This perception of the melody, is used also in an excellent way to write the basic bone-structure of the improvised melody, with as high simplicity as the chord progression. We simply chose one of the closest 7-notes diatonic scales, and we indicate the sequence ofthe melodic centers as ordinal numbers of the diatonic scale.
We summarize some techniques from posts 9, 63,65.
We may define melodic moves not for each chord but for each chord-transition, and preferably for the X7-->x+1 type of transitions (see the symbolism of post 34) e.g. E7-->Am.
Then the chord X7 has only one note x1 for simplicial submelody the starting note of the melodic move, and the end note x2 of the melodic move is the next simlicial submelody note and one note of the chord x+1 not common with the chord X7. If the latter note x2 is not the root of x+1, it is created a tension that has to be resolved later where x2 would be the root of x+1. The tension is highest if the x2 is the 3rd note, middle of it is the 2nd note and resolving if it is the root note. In between the x1 and x2, the rule is that at least 2/3 of the notes belong to the underlying chord, and this can be achieved by repeating notes of the underlying chord if necessary. The move x1->x2 may involve each of the chords X7, x+1 , twice in two octaves each instead of once in one octave only, which may create very impressive melodic effects. This gives an even better opportunity to use in the melodic move, intervals of 8th, 4th and 5th (high harmonic speed, see post 68) , that have higher harmonic score than the other intervals (see post 40). The at most 1/3 of the total duration of the move x1->x2 ,of notes that play with underlying the 1st chord but may be outside the starting chord, might be unusually at chromatic and diatonic speed (see post 68), and sometimes might belong to the next chord or even to none of the two chords. The chromatic or diatonic speed applies usually when approaching the ending note of the melodic move. The melodic moves x1-->x2 can be called chord-transition melodic moves and must have an element of repetition in length and rhythm.
In the traditional Irish melodies that utilize 2-3 only major chords, while the melodic moves are 4-5 or 6-7 , but also in the traditional Greek music of the Aegean Islands, the starting and ending point of the melodic move is during the duration of a single chord and are notes of the chord! But still the rule 2/3 -1/3 for notes internal and external to the chord still holds, and the starting and ending notes of the melodic move may define the simplicial submelody.
We may device a symbolism for a melodic theme move based on the above three factors as follows An1Bn2(-)(x) or An1Bn2(+)(x) where An1 is the first note and Bn2 the last note of the move (n1 n2 denote the piano octave of it) and a minus - or plus + sign if its is sad (minor) or joyful (major) and (x)=1,2,3,4 denotes the dominating density of it is chromatic x=1, if it is diatonic x=2, if it is middle harmonic x=3 and high harmonic x=4 (see post 68) e.g. G5A4(-)(2) . In this way we write the dynamics of he melody as a theme-progression ,much like a chord progression.
VERY SIMPLE MELODIC THEMES OF MELODIC SPEED OF 2NDS AND WITH ONLY ONE CENTAL NOTE OF THE SIMPLICIAL SUBMELODY .
Such melodic themes have as center only one note, usually that of a note of the simplicial sub-melody, and of course usually a note of the underlying chord. The start and end on this note or only end on this note while the waving is by intervals of 2nd. Very simple melodic themes occur often in jigs and reels of Celtic and Irish music, but also of Cretan Lyra music or Pontian Lyra music in Greece.
LONG-SHORT TWO-STEP PATTERN TO COMPOSE A MELODY
A very simple trick to create beautiful melodies like those of Irish songs is to use a two-step rhythmic and melodic scheme of one short-duration note and one long duration (like in ancient Greek language that vowels are divided into two categories long and short duration). The long duration is, say two or three times longer, and the long duration is a note belonging to the chord while the short duration it does not! Usually, the two-step pattern id of diatonic density that is the interval of the two notes is a tine or semitone. But sometimes it may be 3 or 4 semitones, that is, of middle harmonic density. One of the goals of the melody is e.g. to walk down or up an octave or an interval of pure fifth or fourth that is to go from simplicial submelody center to another. In this way, both internal and external bridges among the chords can be created. We compose small ripples of this walking up or down (bridges) by the two-step pattern so that the long note is always a note of the underlying chord. thus given a chord progression we may easily compose such beautiful melodies! If there are lyrics and the lyrics e.g. are in the Greek language we immediately derive an appropriate rippling of the melody. When composing melodies through bridges, the bridges themselves are not sufficient to justify the choice of the chords, and we have to walk through the notes of each chord like harping and between the bridges so as to have a full melody that justifies the particular choice of the chords. But when composing melodies after a chord progression through the 2-step patterns (internal-long, external-short notes for the chord) we walk the octave at the area of each chord, therefore, the melody immediately justifies the choice of the chord.
In the traditional Irish melodies that utilize 2-3 only major chords, while the melodic moves are 4-5 or 6-7 , but also in the traditional Greek music of the Aegean Islands, the starting and ending point of the melodic move is during the duration of a single chord and are notes of the chord! But still the rule 2/3 -1/3 for notes internal and external to the chord still holds, and the starting and ending notes of the melodic move may define the simplicial submelody.
A melodic theme-move, can easily have three factors that characterize it
1) If it is sad (-) or joyful (+) (we may call it minor or major melodic move, although its underground chords sometimes , rarely may be a major or a minor chord respectively).
2) Its melodic density (see the 4 melodic speeds or densities, chromatic, diatonic, middle harmonic and high harmonic in post 68)
4) Its range as an interval (this is related somehow by inequality to the density as in 2). melodic theme-moves that their range is more than one octave are special in stressing the nature of being sad or joyful.
These three parameters still do not define the melodic move-theme even if we know its first note. As we see melodic theme-moves are much more complicated than 3 or 4 notes chords! When creating a melody through melodic theme-moves, ideas similar to those that structure a good chord progression may apply.
VERY SIMPLE MELODIC THEMES OF MELODIC SPEED OF 2NDS AND WITH ONLY ONE CENTAL NOTE OF THE SIMPLICIAL SUBMELODY .
Such melodic themes have as center only one note, usually that of a note of the simplicial sub-melody, and of course usually a note of the underlying chord.

In this way of composing chord-transition melodic moves, the starting ad ending points are of paramount importance. Generally speaking, they are not identical with the centers of the melody, as they do not last in general longer than the other notes. They can be used though to define the simplicial submelody.
The simplicial submelody can be viewed also the channel submelody. With this we mean that the simplicial submelody defines a channel in the pitch-time diagram, where the melody waves. But the shape of the move of the channel is defined by the simplicial submelody. We described how to derive the simplicial submelody from the full melody. But in the harmonic method of composition, the converse is of interest. In other words how to derive a full melody, from the simplicial submelody. And the idea to conceive the simplicial submelody as defining the channel where the full melody waves and being the staring and ending notes of the themes (here usually waves of the channel), is the key to do so. We just sing a waving with small waves that are at 2/3 inside the chord and 1/3 outside it and that start and end at the notes of the simplicial submelody.
We have mentioned in this post that the simplicial submelody is usually the starting or ending notes of simple melodic themes, that can be external bridges of the chord transitions (of density diatonic or middle harmonic etc). Therefore here we apply the 3 basic transformations and starting from a single melodic theme ending to the first note of the simplicial submelody we translate or invert or vary rhythmically thsi theme, and make it end (or start) on the next note of the simplicial submelody. The transformed melodic themes derived in this way cover most often two chords or a chord transition or chord relation
The 3 elementary melodic themes, as we mentioned earlier (e.g. in posts 66 and 69 ) , are the ascending melodic interval of two notes, the isokratic melodic interval of two equal notes and the descending melodic interval of two notes.
1) the translation (either with intervals of 2nd , (or diatonic density) or intervals of 3rd (or middle harmonic density) or of intervals of 4th or 5th (or high harmonic density))
2) The inversion where the ascending move becomes descending.
4) The expansion-contraction or dilation, in which the theme changes melodic velocity or melodic density. In other words while it is by intervals of 2nd it becomes by intervasl of 3rds or 4ths etc, or vice-versa.
3) Rhythm transformation (which may vary)
The 5 basic melodic moves (see e.g. post 69) , being more complicated have more types of transformations, as derived by the writing in a pentagram :
1) Translation
Bach has often used the above 6 transformations in his fugue.
In choosing the simplicial submelody from the chord progression, we have some degrees of freedom, and we may take advantage of them, so as to make the simplicial submelody itself , as an independent melody, to have parts of it that are melodic themes, repeating and transformed by translation, inversion and rhythm variation. Of course, as in the simplicial submelody , we choose on note per chord, these symmetries of the melodic themes, are reflections of the structure of the chord progression and a reflection of the 3 basic relations of chords, namely resolution by 4ths, relative and complementary chords.
In the harmonic method of composition, after the determination of the chord-progression and then the simplicial submelody, the next step is to chose the melodic speed to fill the simplicial submelody to a full melody (see also post 68 for the melodic speeds). If it would be the chromatic speed, it would be an oriental-like melody. If it would be a diatonic speed, it would be a "lazy" an easy to sing melody. If it would be the middle or high harmonic speed, it would be an exotic and beautiful but difficult to sing melody.
In the harmonic method of composition (see post 9) we conversely start with the chord progression, and its chord transitions, we select the starting and ending points of the melodic moves, and then the morphological type of the melodic move , their length , their rhythm , harmonic speeds etc.
The chord-transitional melodic move is as a generalized interval which is defined by the starting and ending notes of the melodic move (and which belong respectively to the starting and ending chords of the chord transition).
The simplicial submelody can be viewed also the channel submelody. With this we mean that the simplicial submelody defines a channel in the pitch-time diagram, where the melody waves. But the shape of the move of the channel is defined by the simplicial submelody. We described how to derive the simplicial submelody from the full melody.

MELODIC THEMES TRANSFORMATIONS AND SIMPLICIAL SUBMELODY

1) Translation
2) Inversion relative to a point
3) Reflection relative to an horizontal line
4) Reflection relative to a vertical line.
5) Rhythm transformation
to the above five we may add the
6) Acceleration-deceleration or Dilation (e.g. from the diatonic speed or density to the middle harmonic speed or density) or Deceleration (vice-versa).
7) Extension in 2 or more octaves
7) Extension in 2 or more octaves
Bach has often used the above 6 transformations in his fugue.
More complicated ways to transform a theme are at least the next 5 and combinations of them (see also post 41)
1) Translate it in different pitches (within a scale or not changing possibly the pitch distances )
2) Translate in time (repeat it)
3) Invert it in time or change its rhythm (if at the begging is slower and at the end faster it will be now the reverse etc)
4) Invert it or distort it in pitch (Create 1st 2nd 3rd or 4th voice versions, utilizing the chord progression as rules of transformation of the theme, or if it is ascending now it will be descending etc)
5) Change it as morphology (from a non-waving ascending it may become waving ascending or isocratic). We prefer spikes and scaling as the main morphological types, while the waving and isocratic as intermediate bridges.
Often melodic bridges from a chord to the next, may start with harmonic speed or density covering the first chord A and then decelerate to diatonic speed or density when reaching to the next chord B

When we have the full melody, by substituting the melodic move with its starting and ending notes we get a simplicial submelody, which shows in a simplified way the general channel move of the melody as a whole, whether it is ascending or descending and how much, and how this is done based on the 3 notes of each of the underlying chords.
It is very instructive to improvise with melodic moves starting and ending at the notes of the simplicial sub-melody , that is at notes of different successive chords (usually at diatonic density) . We may call the external melodic bridges of successive chords. In general this may involve moving on 1 , 2 or more strings. Each part belonging to single string may be called 1-string sub-theme of the external melodic bridge. Most important
are the diatonic density 1-string sub-themes from which a diatonic density melodic bridge may consists
But is also very instructive to improvise with melodic moves (usually at diatonic density) starting and ending at the notes of a single chord . Such melodic moves maybe called internal melodic bridges of the notes of a chord, and again we may define the 1-string sub-themes of the internal melodic bridges. Again most important are the diatonic density 1-string sub-themes from which a diatonic density melodic bridge may consists.
Besides the simplicial sub melody, there is one more note at each chord which is of importance and this is the one note bass, for each chord which is usually one of the two lower frequency strings of the 4-string chord.
The IMPROVISATION OF MONOTONE MESMERIZING MUSIC IS USUALLY a repetitive alternation of two chords, rarely more.
Thus improvisations with one or two notes bass and internal melodic bridges of a chord with their 1-string melodic sub-themes , as in post 72, become important as a single chord may last for quite of a time duration. This IMPROVISATION may be called BASS-AND-INTERNAL BRIDGES OF A SINGLE CHORD.

ASCENDING OR DESCENDING AT WILL THE MELODIC BRIDGES IN CHORD CHANGES.
The alternative positions of the D, A, E shape chords in the 2nd, 3rd and 4th neighborhood of the fret-board (see post 13 ) has a utility by far more than just varying the sound and voicing of the chords! Its main utility is in creating melodic bridges among chords in chord transitions so that the bridge will be ascending or descending from one octave to a higher or lower, without altering its start and end chords! If we had to play these melodic bridges while playing at the same time only open chords we would have to alter ascending such bridges by re-entrance to a lower octave to descending and vice versa. But with the chords distributed among the 3 neighborhoods, we may do as we like with the ascending or descending character of the melodic bridges!
After the chord progression and simplicial submelody we chose,
THE DEFINITION OF MELODIC BRIDGES THAN LINK TWO SUCCESSIVE CHORDS BETWEEN THEM AND START AND END AT THE NOTES OF THE SIMPLICIAL SUBMELODY.
1) WHICH CHORD-TRANSITIONS (PAIRS OF CHORDS) WILL HAVE A MELODIC BRIDGE! (Usually the chord-trasnitions that are in resolutional relation, or resolutional-like relation)
2) THEN WHICH BRIDGES WILL BE ISOMORPHIC IN PITCH AND RHYTHMIC DYNAMIC SHAPE AND WHICH DIFFERENT, DEFINING THEREFORE A PARTITIONING IN THE BRIDGES.
3) THEN IF IN EACH EQUIVALENCE CLASS OF ISOMORPHIC MELODIC BRIDGES IN THIS PARTITIONING, THE BRIDGES ARE EVENTUALLY ASCENDING OR DESCENDING (This besides the emotional significance, determines also where to play the chord in one of the 3 neighborhoods of the fretboard)
4) FINALLY HOW IN EACH EQUIVALENCE CLASS OF ISOMORPHIC MELODIC BRIDGES IN THE PARTITIONING, THE COMPLICATED PITCH DYNAMIC SHAPE OR WAVING AND RHYTHM WILL BE AS A REPETITION OF SUCH PATTERNS OF PREVIOUS ISOMORPHIC MELODIC BRIDGES, OR VARIATION OF SUCH PATTERNAS S SO NOT TO BE TOO BORING. (This pitch dynamic shape has again a significant emotional meaning)
5) THE JUSTIFICATION OF THE CHORD PROGRESSION USUALLY IS NOT DONE BY THE CHOICE OF THE MELODIC BRIDGES (THAT IS GIVEN THE MELODIC BRIDGES MAYBE A SIMPLER CHORD PROGRESSION MAY COVER THEM HARMONICALLY). BUT AN INTERMEDIATE HARPING OR STRUMMING OF EACH CHORD WILL ENHANCE THE MELODY OF THE BRIDGES SO THAT ONLY THIS CHORD PROGRESSION IS JUSTIFIED!
The alternative positions of the D, A, E shape chords in the 2nd, 3rd and 4th neighborhood of the fret-board (see post 13 ) has a utility by far more than just varying the sound and voicing of the chords! Its main utility is in creating melodic bridges among chords in chord transitions so that the bridge will be ascending or descending from one octave to a higher or lower, without altering its start and end chords! If we had to play these melodic bridges while playing at the same time only open chords we would have to alter ascending such bridges by re-entrance to a lower octave to descending and vice versa. But with the chords distributed among the 3 neighborhoods, we may do as we like with the ascending or descending character of the melodic bridges!
After the chord progression and simplicial submelody we chose,
THE DEFINITION OF MELODIC BRIDGES THAN LINK TWO SUCCESSIVE CHORDS BETWEEN THEM AND START AND END AT THE NOTES OF THE SIMPLICIAL SUBMELODY.
1) WHICH CHORD-TRANSITIONS (PAIRS OF CHORDS) WILL HAVE A MELODIC BRIDGE! (Usually the chord-trasnitions that are in resolutional relation, or resolutional-like relation)
2) THEN WHICH BRIDGES WILL BE ISOMORPHIC IN PITCH AND RHYTHMIC DYNAMIC SHAPE AND WHICH DIFFERENT, DEFINING THEREFORE A PARTITIONING IN THE BRIDGES.
3) THEN IF IN EACH EQUIVALENCE CLASS OF ISOMORPHIC MELODIC BRIDGES IN THIS PARTITIONING, THE BRIDGES ARE EVENTUALLY ASCENDING OR DESCENDING (This besides the emotional significance, determines also where to play the chord in one of the 3 neighborhoods of the fretboard)
4) FINALLY HOW IN EACH EQUIVALENCE CLASS OF ISOMORPHIC MELODIC BRIDGES IN THE PARTITIONING, THE COMPLICATED PITCH DYNAMIC SHAPE OR WAVING AND RHYTHM WILL BE AS A REPETITION OF SUCH PATTERNS OF PREVIOUS ISOMORPHIC MELODIC BRIDGES, OR VARIATION OF SUCH PATTERNAS S SO NOT TO BE TOO BORING. (This pitch dynamic shape has again a significant emotional meaning)

In the example below the chord progression is Am E7 Am E7 Am E7 Am E7 Am A7 Dm G7 C F E7 Am and the centers of the melody are correspondingly for each of the above chords the E E E E E B A B A A F G E F D A . The melody-moves consist of 10 notes ,the first 9 belong to the first chord and the last 10th to the next. All the moves are on the chord transitions of the form X->(x+1) in the symbolism of the cycle of 24 chords (see post 34). E.g. E7->Am, or Am->E7, or A7->Dm, or G7->C. An exceptions is the transition F->E7. The notes that belong to the chord for each of these moves are 6 from the 9, that is 2/3 of the notes. They achieve it ,as we said , by repeating notes of the chord. And even in the transition F->E7 the notes hat do not belong to the chord F, while F sounds , do belong to the next chord E7 and so they prepare the ear for the next chord. The melody has all the 4 harmonic speeds (see post 68). They start (ignoring the repeating notes) from the root A of Am and end to the root E of E7,they go back and forth, then from the root A of Am go to the dominant B of E7 and back to the root A of Am. Then they repeat. Then from the root A of Am which is also of A7, they go to the middle note F of Dm. Then from the root G of G7 to the middle E of C. Then from the root of F to the chord F to the 4th note (7th) D of E7, and close back to the root A of Am. Starting from the root of X7 and ending in the middle (2nd note) or dominant (3rd note) of (x+1), (e.g. starting at a of A7 and ending at f of Dm) creates a tension, which resolves at the end of the cycle of 16 moves by ending at the root of minor chord (x+1) (here at a of Am).
Here is the result.

The relation of the starting-ending notes of the melodic patterns as notes of the simplicial submelody and the morphological type of the basic melodic moves are as follows.
1) Straight scaling up or down (including spikes) in one or more of the melodic speeds (straight sadness or joy). Here the notes of the simplicial submelody are the starting and ending notes.
2) Ascending or descending waving (complex sadness or joy). Here the notes of the simplicial submelody are the starting and ending notes.
3) Flat equilibrium waving (serenity and equilibrium emotion).Here the notes of the simplicial submelody are the upper level and lower level ofthe flat channel.
4) Flat diminishing waving (serenity and diminishing emotions). Here the notes of the simplicial submelody are the starting upper or lower level and h ending note of the diminishing channel
5) Flat expanding waving resolving up or down (serenity emotions exploding to either sadness or joy). Here the notes of the simplicial submelody are the starting note and the ending note at the upper or lower level of the expanding channel.
Internal bridges in a chord are nothing else than extended arpeggios. Here is a video about such an internal bridge called blues arpeggio!
