Fix a typo -- I had misrecorded the size of the string x fret block of 31-limit ratios as 4x15, but that's the size of the 13-limit block The 31-limit block is a little bigger.

But whereas a 72-edo guitar would not be, a 36-edo guitar is playable. Neil Haverstick does it.

Among the possible [[skip fretting]] systems for 72-edo, the 27\72 x 2\72 (or equivalently, 4.5\12 x 1\36) system is especially convenient because every ratio in the 31-limit group sans 21 can be played within a block 4 strings wide by 15 frets long. (15 frets of 36-edo is as long as 5 frets of 12-edo, so none of those stretches are unreachable except near the nut.)

(17 frets of 36-edo is shorter than 6 frets of 12-edo.)


The same advantage holds for the 29\72 x 2\72 skip-fretting system, but fourths on adjacent strings are hard to play in that system, because the player must bend one note while playing an adjacent string at the same fret.
