Mt. Herschel is an practiced improvisation using pianoteq in 10 edo and my Korg MS2000 in a close to 10 edo tuning by using keyboard slope. Below is the Melodyne output of a short section of the tuning played “chromatically” with a softer timbre.

There was a preceding experiment using a different keyboard slope tuning – synthesizer only

These pieces started life as a two track improvisation (one with ebow) on a 20 edo guitar that were treated with effects and manipulations. Then the result of this was used to extract midi via Melodyne Single track. This midi was then used to drive two instances of Z3TA+ 2.1 tuned to 10 edo. The synthesized tracks and original audio were then combined to create a polytuned version of the original.

Fantasy for Piano Tuned to 10 edo (with score)

PDF of the score is available by clicking the picture


Fantasy for Piano Tuned to 10 edo started off as an exercise to break try to disrupt common rhythmic patterns. It starts out a bit mad but soon tones down. 10 edo is an interesting tuning because it doesn’t sound as foreign (to me) from 12 as one might expect.

Quantum Mechanics (poly-tuned)

[/caption]Fig. 1: Probability densities corresponding to the wavefunctions of an electron in a hydrogen atom possessing definite energy levels (increasing from the top of the image to the bottom: n = 1, 2, 3, ...) and angular momenta (increasing across from left to right: s, p, d, ...). Brighter areas correspond to higher probability density in a position measurement. Such wavefunctions are directly comparable to Chladni's figures of acoustic modes of vibration in classical physics, and are modes of oscillation as well, possessing a sharp energy and, thus, a definite frequency. The angular momentum and energy are quantized, and take only discrete values like those shown (as is the case for resonant frequencies in acoustics) Fig. 1: Probability densities corresponding to the wavefunctions of an electron in a hydrogen atom possessing definite energy levels (increasing from the top of the image to the bottom: n = 1, 2, 3, …) and angular momenta (increasing across from left to right: s, p, d, …).
