21-tet scale on C (57.14 cent steps). Easley Blackwood, Jr.'s notation for 21 equal temperament. Intervals are notated similarly to those they approximate and there are distinct enharmonic equivalents (E-sharp-down = F-down). MIDI pitch bend matches intervals.
Mystic chord on C as the 1, 11, 7, 5, 13, and 9th harmonics (harmonics 8 through 14, without 12). 1 = C = 0 cents = unison 11 = F↑ = 551.32 cents = eleventh harmonic 7 = B♭ = 968.83 cents = harmonic seventh 5 = E = 386.31 cents = just major third 13 = A♭ = 840.53 cents = thirteenth harmonic 9 = D = 203.91 cents = large just whole tone
Thirteenth chord inversion with no fifth or ninth and the flatted seventh in the bass. Different voicing for guitar. Created by Hyacinth (talk) 14:10, 7 July 2009 using Sibelius 5.
