16-tet scale on C (75 cent steps). Easley Blackwood, Jr.'s notation for 16 equal temperament. Intervals are notated similarly to those they approximate and there are fewer enharmonic equivalents. MIDI pitch bend appears to match intervals (0,56, etc.).
*Octave and septimal chromatic semitone on C = D♭ (Ben Johnston's notation). Just: 21:10 = 1284.47 cents. Limit: 7-limit. Created by Hyacinth (talk) using Sibelius 5 with midi pitch bend on 4,91 for 1284.472656 cents rather than 1200.
*11 steps in 15 equal temperament on C = A↓ (Easley Blackwood's notation). Equal-tempered: 211/15:1 = 880 cents. MIDI pitch bend: 77,57 Created by Hyacinth (talk) using Sibelius 5 with midi pitch bend on ~77,57 on A.
An augmented fifth in just temperment. The first tone is a sine wave of 300Hz, the second is 468.75 Hz, the third is the interval. Made with NCH tone generator
*13 steps in 15 equal temperament on C = A↑ (Easley Blackwood's notation). Equal-tempered: 213/15:1 = 1040 cents. MIDI pitch bend: 102,108 on M6 Created by Hyacinth (talk) using Sibelius 5 with midi pitch bend on ~102,76 on Bb.
*14 steps in 15 equal temperament on C = B↓ (Easley Blackwood's notation). Equal-tempered: 214/15:1 = 1120 cents. MIDI pitch bend: 51,70 Created by Hyacinth (talk) using Sibelius 5 with midi pitch bend on ~179,69 on B.
Secondary dominant with barbershop seventh chords. V/V - V - I in F major (G7-C7-F). Derived from [1]. In just intonation. Sevenths are harmonic sevenths, and the F in the first measure is 27.26 cents lower than the F in the third measure. Pitch bend matches intervals.
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.
It is a constant sound that is made up of two different sounds, one of them having small pauses in the same interval. It was activated with the start button on the treadmill.
