 MELODIC MATHS BY MAX MARTIN AND GERM-PATTERN  SYSTEMS OF CREATING MELODIC THEMES AND MUTATIONS OF  MELODIC THEMES AND RHYTHMS

In the next videos one can see how melodic themes of notes  (but also of chords) and mutations of them plus repetitive combinations of them, can be created by keeping invariant an  initial germ-pattern or  melodic-seed of  interval shifts and pause (GERM PATTERN)  of a note (or chord) or  of  initial pattern of sequence of melodic themes of notes or chords after  seeminly random pauses (omittings) of the parts of the fixed pattern.

Melodic themes of notes can be considered and created also as repettitive combinations of a small set of interval-steps (pitch transformations) in a scale plus a pause wchich may be called MELODIC GERM . A melodic germ  as basic invariant can give many melodic themes with an internal affinity which can  be considered a system of muttations of melodic themes.

This process might be laso conceive as "arpeggiation"  of a muscal melodic theme that serves as germ-pattern of al the derived mutations of it.

Comparing the melody with a speaking language suggests the next correspondence

Let us correspond to each vowel a number of steps inteval shift insidea scale 

E.g. 

empty space=pause 

A=0 step

E= 1 steps

I= 2 steps

O=3 steps

OU=4 steps

Then the content of vowels of any phrase can be translated as a GERM-PATTERN for creating melodic themes as muttaions of this germ-pattern  (and latter also repettitive combinations of them)

AN INTERCATIVE MODE OF VARYING  MANUALLY ON THE TOUCHSCREEN  THE ORDER SHAPE ("DOLPHON WORD" ) OF MELODIC THEMES IS VERY WELL REALIZED WITH THE APPLICATION OSCILAB.   IT IS UTILIZIG ALSO A SUPERPOSITION OF 3 OSCILATIONS OF VARIOUS SHAPES AND CURVES

Applications like Sector (http://kymatica.com/apps/sector)   and Necklace  (https://apps.apple.com/us/app/rhythm-necklace-geometric-sequencer/id954669874  https://www.youtube.com/watch?v=ddWQU6Wo3v8 ) and Chronium
(https://www.youtube.com/watch?v=QYbi4rbMK88)

give in an intearctive way the remarkable ability to the user to variate the rhyhmic pattern  executed by a loop , in other words creating a continously changing or variating  polyrythm. The chronium also allows changingthe pitch and color of the beet as well
