Techniques of Polytempic Polymicrotonal Composition

  Compression of Harmon y in Polymicrotonality One technique regarding the gradual compression of micro-intervallic structures in the microchromatic line is shown below, in Figure 3, from my String Quartet 12 , Big Bad Mother Fucker From Outer Space, 2019.  Figure 1. Tuning Legend from String Quartet #12 String Quartet 12 is explicitly polymicrotonal , with microtonal systems in full, except for the last one. We start with 20tet at 60 cents, 22tet at 54.5 cents, quartertones at 50 cents, and lastly, 18 of the 26tet gamut , at 46.15 cents. Since a starting pitch needs to be chosen for further divisions of the octave of a pitch class set , and inclusive of all other pitch classes within that octave, and for all microtonal systems within the given octaves of each system, I chose C as "1/1" as indicating the "untouched," pure beginning pitch. In this case, the pitch C is from 12tet and is 261.6 Hz. Any pitch class can be used, including a starting pitch up the over...
