Harmonic Series Piano

Sunday, April 2nd, 2017

Raw harmonic series tuned piano

Here is how this piece was made. I played a 12 string electric guitar with a Wampler sustain pedal and Roland Space Echo pedal. Normalized, and reversed that track. Then I used Melodyne to extract a polyphonic midi representation – more or less that same as what the guitar sounded like. Then I added a midi echo effect that is called echo delay which also has a swing setting. The midi output of that was chained into Sonar’s track midi quantization and additional arpeggiator. This midi stream was then into to Kontakt with the tuning set to the harmonic series as show in the photo below.

Now Yer Talkin (JI piano)

Tuesday, August 23rd, 2016

now_yer_talking The score is here.


Now Yer Talkin is a short piece for piano. The composition is through composed. The tuning was developed by Doug Blumeyer and he asked for piano piece. This composition uses the comma shifts in the tuning to a fair degree in the right hand part. The tuning is here as a scala file.

Here is a half-time version to bring out the harmonies a bit more.

chagall[17] Graphic by Scott Dakota August 2016

Scott Dakota developed a new tuning called “Chagall[17]” and I record a Linnstrument improvisation with pianoteq in the tuning as a demonstration. The tuning is below.

(771/256)^(1/3) generator, ~13/9. Superb scale. Like 17&83 temperament in the 2.7.9.11.13.(23) subgroup. Scott Dakota, July 2016.

Piano Exercise in 17 Notes per Octave (August 2016)

Monday, August 8th, 2016

17edo_august

This Piano Exercise in 17 Notes per Octave (August 2016) is another in my series of writing something playable for a piano student that has modest skills in a microtonal tuning. 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. The composition is somewhat free form with development.

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 🙂

Etude for Piano in 22 edo Superpyth [12]

Thursday, July 7th, 2016

etude22


Etude for Piano in 22 edo Superpyth [12] is another in my series of writing something playable for a piano student that has modest skills in a microtonal tuning. Since this tuning is in a 12 note per octave subset of 22 notes per octave the score is to be played as written after setting your sound source to the tuning below. For the sake of comparison the 12 equal version is here.
