Reference notes

This page uses C - D - E - F - G - A - B as reference notes. Play one note at a time so the pitch detector can stay stable.

Better microphone results

Keep Piano close to the microphone, reduce room noise and wait a moment after playing so the pitch can settle.

Common mistakes

  • Playing more than one Piano string or note at once makes detection unstable.
  • Tuning in a noisy room often leads to false readings.
  • Stopping as soon as the note changes without waiting for it to settle can leave the instrument slightly out of tune.
