Template:EDO intro

Theory

384edo is consistent in the 7-limit, tempering out the misty comma [26 -12 -3⟩, and the 5-limit tritriple comma [31 20 -27⟩ in the 5-limit, and 3136/3125, 5120/5103, 250047/250000, and the mistisma 458752/455625 in the 7-limit.

Relation to powers of two

Its adjacent step is known as Pentamu (fifth MIDI-resolution unit, 5mu, 25 = 32 equal divisions of the 12edo semitone). In addition, in light of 384 being a multiple of 32, 384bc val supports windrose temperament in the 7-limit.
