"mutant sruti": _CentoSruti_

CentoSruti *, a "Wabi-Sabi" Temperament ** , is a "mutant variation"
on/of Paul Erlich's sruti tuning-scale system as clearly detailed in "Tuning,
Tonality, and Twenty-Two-Tone Temperament" (originally published in _Xenharmonikon
17_, Spring 1998; revised 4/2/02; available on-line as a PDF file [and highly
recommended "int/dense" reading ;)
I worked this out using various theory & music reference resources AND -
most importantly - using a recently down-loaded vintage early-PowerMac-OS9
softsynth to actually "play around with" this rather spicy, spacey sounding
scale-tuning... now, on to designing and developing my TamburDrone tube-zither...

* _cento_ - Latin, "patchwork garment" -
composition made from quotations of works by other authors
_sruti_ - Sanskrit, "that which is heard"
(relateable to _sutra_ "thread")

* * "Wabi-Sabi" Temperament
a HIHI (Hybrid, Irregular Heretical Intonation) System
_wabi_: Japanese cultural aesthetic term concerning "newness" and
"freshness," "perfect imperfection"; "asymmetry" and
"uniqueness"
_sabi_: Japanese cultural aesthetic term concerning "beauty in age
and patina; oldness, ancient-ness and venerability"

NADA BRAHMA - Sanskrit, "sound [is the] Godhead"
LILA - Sanskrit, "divine play/sport/whimsy" - "the universe is what happens
when God wants to play" - "joyous exercise of spontaneity involved in the art
of creation"

What strange risk of hearing can bring sound to music - a hearing whose
obligation awakens a sensibility so new that it is forever a unique, new-born,
anti-death surprise, created now and now and now. .. a hearing whose moment in
time is always daybreak. - Lucia Dlugoszewski
