'''54-EDO''' is an equal temperament that divides the octave into 54 equal parts, each 22.2222 [[cent]]s in size. It's a rare temperament which adds approximations of the 11th and 15th harmonics, as well as an alternate (flat) mapping for the 5th, to [[27edo]] which it doubles. It is the highest [[EDO]] in which the best mappings of the major 3rd ([[5/4]]) and harmonic 7th ([[7/4]]), 17\54 and 44\54, are exactly 600 cents apart, making them suitable for harmonies using tritone substitutions. The 54cd val makes for an excellent tuning of 7-limit [[Augmented_family#Hexe|hexe temperament]]. | '''54-EDO''' is an equal temperament that divides the octave into 54 equal parts, each 22.2222 [[cent]]s in size.

The immediate close presence of [[53edo]] obscures 54edo and puts this temperament out of popular usage. | |||
