A brief improvisation on the Axis-49 isomorphic keyboard.  The scale is a subset of 29 equal divisions of the octave, steps 5-2-4-2-4, repeating at the 17th degree (perfect fifth of 704 cents), for those interested.

Vegetables You've Never Heard Of

A one-minute piece in The Square Root of 13/10 (a xenharmonic nonoctave tuning) that plays with learning, unlearning, and learning to learn, thru the cryptic story of a pig, a tree, and some tasty truffles.  Co-composed by Andrew Heathwaite and Michael Gaiuranos (aka Snow Leopard) for the UnTwelve 60x60 Mix.

Form and Lyrics:

ROOTING FOR TRUFFLES

UNCONSCIOUS LEARNING

Rooting #1

TREE: As an oak, my roots don’t mind
earth dark bark and dark earth’s ore,
or where roots fruit and bind.

PIG: Truffle o truffle, I snuffle and snuffle
I fumble and rummage for drummage and drummage

Rooting #2

TREE: now new runs leaf here
learnéd neurons whose sounds
sounds like tunes I’d as lief as hear

PIG: Tuber melanosporum,
I dig em, find em, and always score em

Aria:

PIG: So who wouldn’t say
I’m the finest truffle sniffer?
The nose extraordinaire … go away
and peerless … leave me alone
I don’t want that truffle yet.

CONSCIOUS LEARNING

Crisis (Rooting #3)

TREE: To like entails what’s loathed,
so every fork’s a crossroad.
don’t all discriminate?
now I know what people to hate?

Truffles?

Rodan Spiral (WIP)

A simple exercise in singing the intervals of the 11-limit tonality diamond in the context of background harmonic series chords and a moving fundamental.  The bottom note in the melody line stays the same while the top line moves up gradually, first leaping, then stepping.  The solfege system for singing along is as follows:

12/11: fu-so, fu-so
11/10: mi-fu, mi-fu
10/9: re-mi, re-mi
9/8: do-re, do-re
8/7: ta-do, ta-do
7/6: so-ta, so-ta
6/5: mi-so, mi-fu-so
11/9: re-fu, re-mi-fu
5/4: do-mi, do-re-mi
14/11: fu-ta, fu-so-ta
9/7: ta-re, ta-do-re
4/3: so-do, so-ta-do
11/8: do-fu, do-re-mi-fu
7/5: mi-ta, mi-fu-so-ta
10/7: ta-mi, ta-do-re-mi
16/11: fu-do, fu-so-ta-do
3/2: do-so, do-re-mi-fu-so
14/9: re-ta, re-mi-fu-so-ta
11/7: ta-fu, ta-do-re-mi-fu
8/5: mi-do, mi-fu-so-ta-do
18/11: fu-re, fu-so-ta-do-re
5/3: so-mi, so-ta-do-re-mi
12/7: ta-so, ta-do-re-mi-fu-so
7/4: do-ta, do-re-mi-fu-so-ta
16/9: re-do, re-mi-fu-so-ta-do
9/5: mi-re, mi-fu-so-ta-do-re
20/11: fu-mi, fu-so-ta-do-re-mi
11/6: so-fu, so-ta-do-re-mi-fu

11-limit singtervals

Mike Battaglia wanted to hear more music in 15edo and I wanted to record a keyboard jam.

15edo jamdollar

Counterpart to 11-limit singtervals -- a way of practicing the consonant intervals of 9-limit just intonation.  The exercise takes you through the following list, allowing you to sing each interval ascending by leap and by step, following the harmonic series:

10/9: re-mi, re-mi
9/8: do-re, do-re
8/7: ta-do, ta-do
7/6: so-ta, so-ta
6/5: mi-so, mi-so
5/4: do-mi, do-re-mi
9/7: ta-re, ta-do-re
4/3: so-do, so-ta-do
7/5: mi-ta, mi-so-ta
10/7: ta-mi, ta-do-re-mi
3/2: do-so, do-re-mi-so
14/9: re-ta, re-mi-so-ta
8/5: mi-do, mi-so-ta-do
5/3: so-mi, so-ta-do-re-mi
12/7: ta-so, ta-do-re-mi-so
7/4: do-ta, do-re-mi-so-ta
16/9: re-do, re-mi-so-ta-do
9/5: mi-re, mi-so-ta-do-re
