Music & Techniques by Chris Vaisvil

Caleb Morgan on the tuning list posted a piano piece using his 36 note tuning of fractions created in homage to Harry Partch.

I asked and received permission to try his tuning as well as the scala formated tuning itself.

The piece in the video is a sight unseen improvisation using a M-Audio 88es midi controller to drive Pianoteq 3 standalone. I midi recorded the performance via pianoteq and rendered the midi without correction post performance and combined it with video I took of the performance with added effects.

Being an improvisation and a totally new tuning scheme there are “bad” notes and also the exploration section is intact. I can’t say I really grok this tuning though I want to try it again – at an octave or two lower.

Orchestral piece in 22 edo – minimalistic and seems best on headphones

I have been playing with this for about 2 weeks and seem to have come to an impasse. This is a very quirky strange piece – it sounds childish and immature in a way. Reminds me in a very abstract way of the sounds of my neighborhood recorded on my dad’s monaural tape recorder recorded and played back at full amplification.

The technique to compose this piece is to improvise an instrument’s part and then go back as edit as necessary to remove mistakes or correct intonation.

Not done yet – but I can’t move past at this point.
Part of a planned series examining my childhood aural memories.

Watching it Snow is an edited piano improvisation using M-Audio keystation 88es, Pianoteq, Sonar 8.5, and the Hanson 19 scala tuning file (click the “more” below). That the piece is in Just Intonation is actually an accident! Going by the advice I received from Petr Parízek ( tuning list Message #86387 ) to improvise in Hanson I found Hanson_19.scl and proceeded along with no research whatsoever which is how one obtains an inadvertent composition.

This is piece is more melodic than my usual microtonal piece – though I may revise the melody in the beginning sometime in the future to give it more variety.

The score for the piece in pre-translated 12 EDO is here

And here are the intervals those ratios turn out to be. Note – in 12 EDO (“normal” tuning) each half step is 100 cents – so any deviation from 100 cents and multiples thereof (200, 300, ….) is “microtonal” even if the name is the same.

1: 11 25/24 70.672 cents classic chromatic semitone

This is a hybrid performance / scored piece using Kontakt 3, pianoteq, sonar 8.5, and a Korg MS2000 as a midi controller.

Kontakt contributes drums, upright bass, sax section, and trumpet.

Pianoteq 2.3 contributes the jazz piano.

The drums were scored first, bass second and then other instruments played along with that. The goal was to keep the composition to 60 seconds or less since this is a submission to the Chicago 60×60 event (not selected at this time).

The main motive is a 17 ET analog to a suspended 4th to major 3rd in common practice 12 edo tuning.
