53 commas and 12 equal divisions
Each pitch’s distance from Rast was converted to cents with 53 equal commas and compared with the nearest note of Western music’s 12 equal semitones (Rast = G). The deviation shows how many cents the pitch is above (+) or below (−) that note; 1 comma is about 22.6 cents, a semitone 100 cents. Tap a row to hear the pitch.
