Why it works
Changing between chords quickly is what makes songs possible. Counting your changes turns practice into a game — and shows you improving day by day.

Best scores and your practice streak are saved in this browser. No account needed.
Listen mode
Hears your chords through the microphone and counts changes for you. Sound is analyzed on your device and never recorded or sent anywhere.

How to do one-minute changes

  1. Pick two chords you’re learning. Play each one slowly first so you know the shapes.
  2. Press Start, then switch between the two chords as many times as you can in one minute — strum once each time you land a chord cleanly.
  3. Tap the button (or press Space) every time you change. Only count changes where every note rings.
  4. Do it once a day. Your score will climb fast — 30 changes a minute is a good goal before moving on.
  5. In Listen mode the trainer uses your microphone to hear which chord you’re playing and counts each change for you. Strum every chord clearly and let it ring; changes with muted or buzzing strings may not count — which is the point. If it misses one, tap to add it.
  6. In Play along mode, the chords switch in time with a click: land each chord on the beat.
