37 edo Aeolian Harp Prelude is a piece composed by modifying with Melodyne a electric aeolian harp drone chord played by the wind. The approximate original tuning was re-tuned to 37 edo from an imported a scala file I made and then the piece composed by adjusting the individual notes.

Aeolian Edit 2 is an experiment with manipulation of an electric aeolian harp sample which I added counterpoint and retuned to 17 edo (equal division of the octave). Since the electric aeolian harp yields only harmonics what has been manipulated are the pitch values that the melodyne detection routine decided were root pitches and *not* harmonics. By retuning to 17 I have recomposed the original content into something other than a pure harmonic relationship. My apologies for the large volume changes – in this case I’d rather have close to a constant loudness but do not have that worked out yet.
Not for the faint of ear!!
Rock Trio in Harmonic Series is an extreme recomposition of the Nevadatite material put into the context of rather heavy and dissonant rock trio of guitar, bass and drums using the raw unreduced harmonic series and the idiosyncrasies of Kontakt.
Tesseract is a recomposed piece that started life as an steel string 12 equal acoustic guitar improvisation trapped in an unpublished video. I extracted the audio track and then brought it into Melodyne 4 Multitrack. Once there I duplicated the track and transposed the duplicate up a fifth creating a lot of lush harmonies. Then to polish the harmonies I selected both tracks and applied Melody 4’s adaptive JI algorithm. Applying adaptive just intonation to the combined tracks is crucial to allow the programming to operate on the newly created fifth relationships. Lastly I panned the two tracks left and right.
Spectral Greetings is a piece that started as a Linnstrument improvisation and then was harmonically filtered with Paul’s Extreme Stretch at the above frequencies to create a justly tuned spectral piece when all four frequencies were combined. The score is represented by the sound spectrum.
The Indecision is reworked improvisation in a tuning Scott Dakota posted as a Just intonation interpretation of Nordic Folk interval chart by Steinar Ofsdal.
Banana Equivalent Dose is a recomposition of three 12 equal guitar tracks stolen from a 12 equal project and retuned to the JI tuning below in Melodyne and then mastered with effects. The piece is a bit noisy and opinionated.

The Loop is an experiment in audio manipulation. It was made by taking sections from a 17 edo electric guitar recording and manipulating the individual notes to change the harmonies and sequences in Melodyne Single Track using their “Direct Note Access” with the Melodyne tuning set to 17 edo. Then the 10 fragments were stretched with Paul’s Extreme Sound stretch. After that the fragments were arranged into two stereo tracks in Sonar, effects applied, exported and normalized.
This is not nice melodic music
– it is a harsh exploration of a technique!
even the best of intentions is an exercise in transforming audio. I used a sound effects CD ripped to my iPod as the source for the Korg MS-20 mini’s signal in. While it played I manipulated the settings on the synthesizer. If you listen closely you can at times hear a bit of the original signal leaking into the output. Except for editing out silence I applied no effects or other manipulation of the output.
