How to tune a violin in 3 steps

  1. Press the microphone button and allow microphone access when your browser asks.
  2. Start with the A string. Bow it or pluck it and let it ring. The tuner shows the note and a needle: left is flat, right is sharp.
  3. Turn the peg for large changes and the fine tuner for small ones, until the needle stays in the centre. Then tune D, G and E.

Tips for tuning a violin

  • Hold the phone or laptop 20–30 cm from the violin, near the f-holes, in a quiet room.
  • A long, even bow stroke gives a steadier reading than a short pluck.
  • Tune up to the note: if a string is sharp, loosen it a little below the note and bring it back up. The string stays in tune longer.
  • Many orchestras tune to A4 = 442 Hz. Tap “A4 = 440 Hz” under the tuner to change the reference pitch.
  • Without a microphone, tap a note button under the menu to hear its reference tone and tune by ear.
