Hard-of-basic tunings have [[Semifourth|semifourths]] as generators, between 1\5 | Hard-of-basic tunings have [[Semifourth|semifourths]] as generators, between 1\5 (240¢) and 3\14 (257.14¢), where two of them create a diatonic 4th. The generator could be viewed as a 15/13, and the resulting "ultramajor" chords and "inframinor" triads could be viewed as approximating 10:13:15 and 26:30:39. See [[Arto and Tendo Theory]]. | ||
