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

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.

Claire de Lune in Wilson’s Golden Horagram nr.1 tuning

Claire de Lune in Wilson’s Golden Horagram number1 tuning using u-he‘s Diva I think shows some of the amazing attributes of Wilson’s tuning systems. Throwing an arbitrary 7 note tuning and coming up with (for a microtonalist) very listenable result is impressive. I hope you enjoy this transtuned rendition as music as I have. The tuning is below.

Micronation (Melodyne processed aeolian harp )

March 11th, 2017



Micronation is an audio experiment where I took a ~30 seconds of aeolian harp captured during a high wind event and used Melodyne to determine each of four root notes by frequency. [The strings were tuned justly by ear but drift after several hours exposure to the elements outside, especially due to temperature changes] Then I used Paul’s Extreme Sound Stretch to isolation each vertical harmonic structure based upon the roots determined by Melodyne (10 harmonics high by 25 cents wide)and exporting the four files. Then I used Sonar to sequence the exported wav files and applied reverb, EQ, and tape simulation. The experimentally determined roots are 92 Hz, 118 Hz[59/46], 140 Hz[35/23], and 184 Hz [ 2/1 the octave of 92].
