Hi, I'm Tristan Bay, a microtonal electronic musician living in Portland, Oregon, USA. My stuff can be found at https://tristanbay.com.

JI scale dump

Here are some just intonation scales I've been collecting. All of them are constant structure (i.e. the same just interval is always represented by the same number of scale degrees) and repeat at the octave.

Boutique scales (less than 12 notes)
