Omnitetrachordal MOS scale

[[5L_12s|5L+12s]]

17 tones (7+3+7)

[[Superpyth|Superpyth]] / ultrapyth MOS.  Imperfect, best at low L/s.  Many modes may be split two ways.

[[Gallery_of_omnitetrachordal_scales#perfect|P]] = 0.2600167527

[[Gallery_of_omnitetrachordal_scales#Q|Q]] = 6.9100586343 (4/3 = 2L+5.5s)

L = 70.59 to 240.00 cents (178.13 cents @ Q)

s = 0.00 to 70.59 cents (25.78 cents @ Q)

9/8 = L+2s (211.76 to 240.00 cents)

4/3 = 2L+5s (480.00 to 494.12 cents)

generator = 4/3

notable EDOs: 22, 27, 32, 37, 39
