'''[[Edt|Division of the third harmonic]] into 54 equal parts''' ( | {{Infobox ET}} | ||
'''[[Edt|Division of the third harmonic]] into 54 equal parts''' (54EDT) is related to [[34edo|34 edo]], but with the 3/1 rather than the 2/1 being just. The octave is about 2.4728 cents compressed and the step size is about 35.2214 cents. It is consistent to the [[7-odd-limit|7-integer-limit]], but not to the 8-integer-limit. In comparison, 34edo is only consistent up to the [[5-odd-limit|6-integer-limit]]. | |||
== Commas == | |||
This tuning tempers out [[50/49]] and [[64/63]] in the [[7-limit]] and [[78/77]] in the [[13-limit]]. | |||
