Lumatone mapping for 38edo

From Xenharmonic Wiki
Jump to navigation Jump to search

38edo is an interesting case for Lumatone mappings, since (like 24edo), it is not generated by fifths and octaves, so the Standard Lumatone mapping for Pythagorean only reaches 19edo intervals. Even the b val does not generate a diatonic or antidiatonic scale, and the bb val is very flat indeed.

Instead, as slicing the perfect 5th in two results in an essentially perfect 11/9, it makes a lot of sense to use the neutral thirds mapping.

Or if you want greater range while still reaching a lot of good intervals in few steps the astrology mapping works well.
