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.).
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.
A12 4 7 10 on C. Traditional notation: C B♭ E. MIDI pitch bend matches intervals. Other non-octave tunings investigated by Bohlen besides the Bohlen-Pierce scale include twelve steps in the tritave, named A12 by Enrique Moreno [1] and based on the 4:7:10 chord.

Chromatic fourth in Johann Sebastian Bach's Well-Tempered Clavier (the chromatic fourth is indicated by a red bracket). From Fugue No. 2 in D minor of the second book of Bach's Well-Tempered Clavier (BWV 875). Entered into Finale 2006, with red bracket added in Photoshop. The music this excerpt comes from is public domain. My selection and addition of bracket is GFDL.
