A tuner, notation exercises, rhythm check, playable piano and a binaural resonance tool — all in one place.
Pick your instrument (or voice), allow microphone access, and play or sing a note to see how in-tune it is.
Click any note to hear its pitch and see its name. Notice how the notes climb continuously from the bass staff up through the treble staff.
Which note is shown on the staff?
Listen to the click track, then tap the drum on every beat.
Play with your mouse or finger — or your computer keyboard using A S D F G H J K for the white keys and W E T Y U for the black keys (C4–C5). The lower octave (C3–B3) is mouse/touch only.
Rec starts a 4-beat count-in then records 4 measures (16 beats), looping automatically once done · Play stops or restarts the loop · Mute silences it without losing it · Clear erases it. Only one track can record at a time — start a second while the first is looping to layer sounds. Clear all tracks to change the tempo.
Try: record Track 1, hit Play, then record Track 2 or 3 on top while it loops.
Generate binaural beats for focus, relaxation or meditation. Use headphones for the full effect — each ear receives a slightly different frequency.
For best results use stereo headphones. Binaural beats work by sending a slightly different tone to each ear; your brain perceives the difference as a rhythmic pulse.
