Step by step

  1. Allow microphone access when your browser asks (audio stays on your device).
  2. Play one note and let it ring. The tuner detects which string or note you are playing.
  3. Follow the needle: left means flat (tighten / raise), right means sharp (loosen / lower).
  4. When the note turns green you are within ±3 cents. Move on to the next one.

Pro tip

Use the fine tuners for small corrections and the pegs only for big ones, pushing the peg in as you turn.
