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is a recomposed piece that started life as an steel string 12 equal acoustic guitar improvisation trapped in an unpublished video.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.
