Selected Major Triads in Easley Blackwood's 15-Note Equal Temperament

Blackwood's notation for 15 notes (also known as 15-EDO for "15 Equal Divisions of the Octave) can often seem very strange. The A major and B-flat major triads below are enharmonically equivalent; the "raised-G" and "raised-A-flat" triads are enharmonically equivalent as well.
