Microtonal Keyboards

3 microtonal keyboards:

Bohlen-Pierce - Dur II: (The Bohlen-Pierce scale: This scale divides the tritave (octave+fifth) into 13 steps. I’m just discovering many interesting intervals which can not be found in the 12-tone equal-tempered scale. It contains consonant harmonies based on the odd harmonic overtones 3:5:7:9. However, a pure octave is not present (extraterrestrial!). Thanks to Elaine Walker for the support.)
