Interval calculator

Choose two pitches: see the number of commas between them, the interval's name and its makeup in bakiye, mücenneb and tanini steps, its size in cents and its frequency ratio. Listen to them one after another or together.

Tapping a key on the keyboard changes the pitch in the selected box; the selection then moves to the other box on its own.
