Etudes Recital 180324

POSTLUDE V (Live recording of premiere, St. Mary Redcliffe, Bristol, 13 February 2020)

An augmented sonification of Kyle Gann's Anatomy of an Octave (the extant condensed version with 580 pitches) in the form of a catalog piece. All 580 ratios are played against a 240Hz base pitch, one at a time from low to high with a duration of 7 seconds each, with additional chord tones derived from the frequencies (combination tones, Pythagorean means, etc.) using my Implication Organ instrument in Csound. I recommend downloading before listening to get the highest quality sound.

This piece is also on YouTube: https://www.youtube.com/watch?v=697lo5twu5A

Thanks to Kyle for his work, and for giving me the go-ahead to publish this piece and approving the title.

For more information about the list of ratios, see Kyle's excellent book The Arithmetic of Listening (https://www.amazon.com/Arithmetic-Listening-History-Impractical-Musician/dp/0252084411). Also, listen to his music!

I had intended to publish this on Bandcamp, but the file exceeds their upload limits. But you can consider supporting me by buying one of my other releases at https://mysterybear.bandcamp.com/

Gann's Anatomy

Physically modelled performance (NotePerformer) 
Orchestral music in 13-limit just intonation
(3.3.3.3/4.3.3.1/bd.timp.harp/strings)

N.B. The very last chord is to be played "as long and accurate as possible", with multiple asynchronous reattacks in the brass and strings (in this version, there is a simple fade out due to the limitations of physical modelling etc.)
