How to tune a viola

  1. Press Start Tuning and allow microphone access when your browser asks.
  2. Play one note. Pluck a single string or play one key, close to the microphone, and let it ring.
  3. Read the display. The big letter is the nearest note. The bar shows how far off you are: left is flat (tune up), right is sharp (tune down).
  4. Turn until it goes green. Inside your tolerance (±3 cents by default) the display turns green and the string gets a check mark.

Tips

  • Tune the A string first, then D, G and C.
  • The low C string can sound quiet on phone microphones. Bow firmly near the bridge for a clear reading.
