Omnitetrachordal MODMOS scale


24 tones (10+4+10)

mohajira / neutral-thirds; 2 forms; imperfect; best at low L/s

P = 0.5872804832

Q = 5.8650213288 (4/3 = 3L+6.5s)

L = 50.00 to 171.43 cents (121.23 cents @ Q)

s = 0.00 to 50.00 cents (20.67 cents @ Q)

9/8 = L+3s (171.43 to 200.00 cents)

4/3 = 3L+7s (500.00 to 514.29 cents)

MOS generator = 2L+5s (342.86 to 350.00 cents)

notable EDOs: 31, 38, 45, 55, 69
