Tap a tile to hear its tone. Tap two tiles to swap. Order them from lowest to highest pitch.
About Hearsort — ordering pitches by ear
Hearsort trains relative pitch ordering — ranking several tones from lowest to highest by ear alone. Putting pitches in order is the backbone of reading a melody's shape, arranging voices from bass to soprano, and knowing at a glance whether a line rises or falls.
Tap a tile to hear its tone, then tap two tiles to swap them. Keep rearranging until the row runs from the lowest pitch on the left to the highest on the right. There is no time limit, so you can audition any tile as often as you need before committing to an order.
Pitch height comes from frequency, measured in Hz. Our guide to what frequency is connects the physics to what you hear. See the full library of ear-training guides for more.
