I’ve hovered around just intonation for a little while, but never truly dived in …. until this week. I’m using Partch’s 43 tone scale dumbed down to a 41 tone scale upon Kraig Grady’s advice (which I understand comes from Erv Wilson’s writings). Kraig also designed the layout of the pitches in my little iPhone interface … see below.
The JI sounds are beautiful!
I thought it would be inaccessible to my ears. But it is not. When two pitches are very close it creates a kind of phasing which appears to give the note a spatial depth. I wonder if this actually accidentally fakes a spatial audio cue. Here’s a quick play around:
Coloured squares represent tones which have the closest whole-number relationship with the tonic (which is in light blue). You can perceive the coloured tones as being kinda-like a major scale in equal tempered 12 tones.
I had one of those other-wordly moments, the first time I played with this little interface, because it sounds awfully similar to one of my favourite Aphex Twin tracks:
