Omnitetrachordal MODMOS scale


17 tones (7+3+7)

Mohajira / neutral-thirds MODMOS; 2 forms

P = 1.5872804832

Q = 6.8650213288 (4/3 = 3L+3.5s)

L = 70.59 to 171.43 cents (90.22 cents @ P, 141.90 cents @ Q)

s = 0.00 to 70.59 cents (56.84 cents @ P, 20.67 cents @ Q)

9/8 = L+2s (171.43 to 211.76 cents)

4/3 = 3L+4s (494.12 to 514.29 cents)

MOS generator = 2L+3s (342.9 to 352.9 cents)

notable EDOs: 24, 31, 41, 65
