The 19th Sky of Semaphore

Saturday, April 8th, 2017


The 19th Sky of Semaphore is a composition for an imaginary chamber ensemble of two semaphore 19 tuned pianos. Photo by Chris Vaisvil
For comparison I present the same piece in 19 edo. If you listen closely you can hear slight beating in the opening 5th of the piece in the 19 edo version but is not present in the sempahore19 version.

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.

Re-composition in 26 edo of Debussy’s String Quartet, Movement 1

Monday, March 13th, 2017

Picture by Chris Vaisvil


Using the first movement of Debussy’s string quartet I trans-tuned from 12 to 26 notes per octave and further developed the derivative by transposition and tempo adjustment. The result, to my ears, is much more early 21th century than late 19th century string quartet.
