Piano Exercise in 17 Notes per Octave

Wednesday, May 18th, 2016

exercisein17

Piano Exercise in 17 Notes per Octave is an attempt to write something playable for a piano student that has modest skills. The score is purposely scordatura because I think that notating in various microtonal accidentals is simply a burden when a person with a 12 equal midi controller and microtonal aware sound source set to 17 notes per octave (like a free Xen-Arts VSTi) can simply play the score as if it was written for 12 equal but the sound will be in 17 equal and produce the microtonal music of the score. A note on the composition – it is a of a nested ABA’B’ form.

The full score is here. Academic performance in a setting where a fee is charged is allowed. Any other commercial use without my permission is not. Please write me for permission in such a case, I haven’t told anyone no as of yet 🙂

Thank you Neil Haverstick for suggesting this project.

Mt. Herschel is an practiced improvisation using pianoteq in 10 edo and my Korg MS2000 in a close to 10 edo tuning by using keyboard slope. Below is the Melodyne output of a short section of the tuning played “chromatically” with a softer timbre.

phi[8] piano improvisation

follow along score, 8th note reduction

phi[8] piano improvisation is an improvisation in the tuning below. The tuning has two basic interval sizes, ~108 cents and ~175 cents. This would lead you to believe that the tuning is not very harmonious. I found it to be otherwise and also excellent for melodies.

Jake asked for the same improvisation in “minor” mode – the tuning is below.

The tuning was devised by Jake Freivald – phi[8] is a LSLLSLSL mode “major”
