Incidental Music for an Eclipse

Sunday, August 20th, 2017



Incidental Music for an Eclipse is a piece performed by Chris Vaisvil

Tuning is a mixture of raw harmonic series based on C and Wendy Carlos’ twelve note scale based on octave-repeating harmonics on A. A = 1/1
(440 Hz). 1/1 17/16 9/8 19/16 5/4 21/16 11/8 3/2 13/8 27/16 7/4 15/8

A Figure in a Field (album)

Thursday, July 27th, 2017

I have finally released my album “A Figure in a Field”. It is a mostly ambient leaning album in many tunings and created with many techniques. See the album and track notes for details.

Harmonic Series Piano

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.

Micronation (Melodyne processed aeolian harp )

Saturday, 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].

off tracks age is an aeolian harp sample that was recomposed by using Melodyne 4’s adaptive Just Intonation and rhythm normalization functions and then the exported result was modified using Native Instrument’s Guitar Rig 5 and Cakewalk Sonar’s Breverb.
