Appendix E: Alternative Tunings

16. Harry Partch 11-Limit 43 Note Just Intonation

One of the pioneers of modern microtonal composition, Partch built

a unique orchestra with this tuning during the first half of the 20th

century, to perform his own compositions. The large number of intervals

in this very dense scale offers a full vocabulary of expressive chords

and complex key changes. The narrow spacing also allows fixed-

pitched instruments like marimbas and organs to perform glissando-like

passages. G = 1/1 (392 Hz, MIDI note 67)

1/1 81/80 33/32 21/20 16/15 12/11 11/10 10/9 9/8 8/7 7/6 32/27 6/5 11/9

160/81

17. Arabic 12-Tone

A 12-tone approximation of an Arabic scale, which appears in some elec-

tronic keyboards designed for use with Arabic music. Not a JI scale, nor

equal tempered. These are the intervals in Cents relative to C:

60 = Cents  0
61 = Cents +151
62 = Cents +204
63 = Cents +294
64 = Cents +355
65 = Cents +498
66 = Cents +649
67 = Cents +702
68 = Cents +853
69 = Cents +906

70 = Cents +996

71 = Cents +1057

72 = Cents +1200
