- Delta scale

The δ (delta) scale is a non-octave repeating musical scale. It may be regarded as the beta scale's reciprocal since it is, "as far 'down' the (0 3 6 9) circle from α as β is 'up.'"[1] As such it would split the minor second into eight equal parts of approximately 14 cents each
Play (help·info). This would total approximately 85.7 steps per octave.
The Bohlen-Pierce delta scale is based on the tritave and the 7:5:3 "wide" triad (
