How to use a tuner:

  • Turn on your tuner.
  • It should be set to tune at A440, the frequency used most often to tune. If not set correctly, the tuner should have a guide to change this.
  • Make your pitch with one good, long, strong sound.




  • Observe which way the needle moves:
  • Left = Flat: The pitch is too low
  • Right = Sharp: The pitch is too high
  • Adjust your instrument as needed.
  • Strike your pitch again to test the adjustment.

Once the needle is in the center, the pitch is in tune.

Depending on the tuner your choose, a green light may light up when your pitch is in tune.
