By Any Other Name is a 31 note per octave rock band composition using several tracks of 31 note per octave bouzouki, fretless bass and drums. The music makes use of the consonant 3rds that 31 edo provides as well as its hyperchromaticism.

A Touch of Blues (in 31 edo) is an improvisation on Andrew Heathwaite’s 31 edo bouzouki. It has an odd stereo field created by using a cheap guitar sound hole pick up and a microphone both hard-panned left and right respectively. The pick up placement is shown in the graphic above.

Please Don’t Forget – 31 edo Bouzouki and Vocal Improv with video

Sunday, July 27th, 2014

Please Don’t Forget is an improvisation (vocal line, words and bouzouki) based upon some chords I found when tuning the instrument to G C E C’. The instrument is on loan from Andrew Heathwaite and is being thoroughly enjoyed! No slide was used. It seems the small 39 cent steps in 31 give the glissando the illusion of being portamento. Full quality video is here.

MEANTONE
http://xenharmonic.wikispaces.com/Meantone+family

We all know the basics of meantone, so I won’t go into a lot of detail. Septimal meantone takes us to 7/4 by stacking 10 fifths — 7-limit intervals are complex / costly / precious.

Meantone[19] in 31 EDO (i.e., using 18\31, or the 18th step of 31 EDO) gives us lots of accurate 8/7s, 7/6s, 7/4s, 7/5s, 10/7s, and so on. The 9/7 is about 10 cents flat. A few neutrals creep in.

This is the “Ionian” mode: If you play the 1/1, 9/8, 5/4, 4/3, 3/2, 5/3, 15/8, and 2/1 of this mode, you’ll have a standard 5-limit major scale. You can do a I-IV-V, ii-V-I, etc. using this scale.

Andrew’s 5-2-2 in 31 edo (for piano)

Wednesday, June 19th, 2013

click me for the scala file

This is a second (or third) try at putting together an improvisation tonight for Andrew Heathwaite’s 3 (count ’em three!) note subset of 31 edo – which I mapped to all white keys using the 7 note .kbm that came with pianoteq. I call it simply Andrew’s 5-2-2 in 31 edo (for piano) And here is the midi of my performance for the very curious to roll their own scordatura. Click the picture for the scala file.
