Pseudo-Isomorphic Pseudo-Diatonic

A pseudo-isomorphic pseudo-diatonic mapping for 32edo that duplicates note 0 as note 32 in a mapping taken from 33edo yields an alternate approach to diatonic playing, as demonstrated in 32edo improv (2025).

Sixix

Note that since 32edo is a ultrapyth temperament, the best approximation to 5/4 is a doubly-augmented unison, which makes for awkward fingerings. The sixix mapping makes the 5-limit as easily accessible as possible.

Compressed

The compressed mapping maximizes the range at 8½ octaves (which slope upwards slightly) with no missed notes and no repeated notes.

Expanded

Although the compressed Sixix mapping for 32edo is the most efficient in terms of getting range without missing notes and has only a gentle octave slope, the lack of vertical repeats may cause trouble at vertical wraparounds, and some fingerings are still awkward. Bryan Deister has demonstrated a 4L 3s mapping (with a 5:4 step ratio) that is more relaxed, in Licorice Hearted - 32edo (2026) ([short 1]; [short 2]), although with different placement of the first MIDI note 0. Both the flat (best) and sharp (second-best) approximations of the classic major third ~5/4 are easily accessible (although the flat approximation is slightly easier), as is the (sharp) fifth ~3/2. The contiguous range is just under 5¼ octaves, with a moderate downwards slope.

Amity

Bryan Deister has used a 6L 1s (with a 5:2 step ratio) Amity mapping for 32edo, in Lost Woods - Legend of Zelda (microtonal cover in 32edo) (2025). The Amity generator acute minor third 9\32 is too sharp to map as ~6/5 and instead is mapped as a flat neutral third ~11/9. Both the flat (best) and sharp (second-best) approximations of the classic major third ~5/4 are easily accessible (although the sharp approximation is a bit easier), as is the (sharp) fifth ~3/2 (which is, however, oddly more in line with the flat major third, whereas Amity temperament for 32edo specifies the sharp major third, in the 32c val). The range is just over 4½ octaves, with a mild upwards slope.
