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.

Improv in 29edo :: 2013-10-15

An improvisation on the cura saz, tuned to a 13-limit Just Intonation scale.

2014-01-21 Cura Saz Improvisation

I have the great good fortune to live a few blocks down from xenharmonic legend Daniel Stearns, who lent me his tenor ukelele, refretted to an 8-tone-per-octave subset of 13-tone equal temperament.  The open string tuning, for those interested, was *not* a subset of 13-equal, but rather an approximation of the harmonic series 8:9:11:12, that is, the frequency ratios 1/1, 9/8, 11/8 and 3/2.  I recorded this improvisation in bed on March 13, 2014.  It is dedicated to Dan Stearns.

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?

Music by Andrew Heathwaite, words by Carey Smith.  A four-part vocal round in 7-limit just intonation.

i am short
i had a dream
that i was big
i towered over everyone
i was a monster
i felt scarred and hideous
i was glad to wake up
and be small
so small i fit
in the bottom
of a teacup

I am short

A tour of some unique polyrhythms based on the Stern-Brocot sequence (https://oeis.org/A002487).  Every bar features a polyrhythm between tom and snare based on pairs of numbers from:

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.

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
