Here's a rendition of Bach's C Major Prelude and Fugue (opening) played in Just Intonation on a TPX4s Tonal Plexus keyboard. Obviously, Bach did not write this music to be played in Just Intonation (the "Well Tempered" part of "Well Tempered Clavier" has a specific meaning for tuning), so this is an experimental performance which uses pure 3rds and 5ths, natural 7ths in dominant chords, and harmonics reaching the 17-Limit in diminished chords. In several places, a common tone can be heard to 'bend' from one chord to the next (usually in ii-V progressions) where a pitch has to move by a septimal comma; the pitch is changing in real time by JND steps. This is a single take. I played only the opening of the fugue, very slowly ; ) This is for two reasons. First, so my fingers will behave and play the right keys, and second, so the sounds of Just Intonation can be savored a bit. Enjoy!

For some reason this green TPX4s was speaking to me in various flavors of Gm7 chords. So I was messing around with them and came up with this. The sounds are coming from the TPX internal synth, except for the drums. It's basically just four chords repeating with an otherwise unoriginal diatonic melody. The interesting thing about it to me is that the motion from the last chord back to the first is a modulation between two versions of a Gm7 chord which are two commas apart, so it's a weird example of what is usually called an enharmonic modulation in music theory. I hope you like it. 350c69d7ab
