Diachrome is interesting for having at least two notable JI interpretations. In both interpretations below, L + s = 9/8, and m = 256/243.

In the 7-limit, diachrome has two JI tunings which are very similar and can be identified by tempering out [[5120/5103]], the 5.8c gap between 81/80 and 64/63, the two most common interpretations for "aberrisma" scale steps in [[aberrismic theory]]:
