202. RHYTMIC MICRO-THEMES AND IMPROVISATION OF THEM IN MELODIC IMPROVISATION

RHYTHMIC  MICRO-THEMES AND IMPROVISATION OF THEM.

And see post 486, about chromatic arpeggios over a chord (and chord-scale).

The chord 7-scale is split to 5-string + 4-string parts. 

We substitute the voice melody M of the song with a simplicial submelody SM of it. Each note of the simplicial submelody is a note of the underlying chord. Then we extend the simplicial submelody SM, with small oscillations (within the 7-note chord-scale) 4 times faster, around each note of the simplicial submelody. The result is the chromatic arpeggio CA-SM, which on the island of Crete is also called "condilies." 

The pattern of the oscillation determines the style-signature of the condilia

At another side nevertheless, such fast dancing solos have a "projection trace" to the rhythm exclusively as note durations and position in time irrespectively of what pitch is each note. Then the melodic micro-themes or "rotations" ("gyrismata" or  "strofes") become rhythmic micro-themes, and the melodic improvisation of them becomes rhythmic improvisation. Such rhythmic improvisations obviously could be carried out with single note or on percussion instrument only (see Djembe music). When one tries to compose or improvise such melodic "rotations" the underlying rhythmic micro-themes and their variations are of primary importance as they choose where in time you put a note and how long it would sound. having chosen the rhythmic micro-themes and their variations will greatly make easy the final choice of the pitch too of each not and the melodic patterns. The rhythm here will be like a road of the mountains where we eventually drive our melodic vehicle , and this "road" is not straight by changing directions and slopes. The rhythmic variations are similar to the melodic themes variations: They have inversions in time, translation of patterns in rhythms increased or decreased by powers of 2, and mutations.

Of course tap-dancing is the best natural example of such RHYTHMIC  MICRO-THEMES AND IMPROVISATION OF THEM.
