This produces a twelfth-tone tuning, with the whole tone measuring 200 cents, the same as in 12-tone equal temperament. 72-tone is also a superset of [[24edo|24-tone equal temperament]], the standard tuning of most Arabic music. | ||
Composers that used 72-tone include Alois Hába, Ivan Wyschnegradsky, Julián Carillo (who is better associated with [[96edo|96-edo]]), Iannis Xenakis and the jazz musician Joe Maneri. | |||
72-tone equal temperament approximates 11-limit [[JustIntonation|just intonation]] exceptionally well. The octave, fifth and fourth are the same size as they would be in 12-tone, 72, 42 and 30 commas respectively, but the major third (5/4) measures 23 commas, not 24, and other major intervals are one comma flat of 12-et while minor ones are one comma sharp. The septimal minor seventh (7/4) is 58 commas, while the undecimal semiaugmented fourth (11/8) is 33. | |||
