Something wrong?

Tune your mandolin with the microphone of your phone or computer. The mandolin preset is already selected: press the microphone, play one string, and the tuner shows the note and whether it is too low or too high.

The mandolin has eight strings in four pairs. Both strings of a pair are tuned to the same note (unison), like the four violin strings.

How to tune a mandolin in 3 steps

  1. Press the microphone button and allow microphone access when your browser asks.
  2. Pluck one string of a pair and mute the other with a finger. The tuner shows the note and a needle: left is flat, right is sharp.
  3. Turn the tuning key until the needle stays in the centre. Then tune the second string of the pair, and continue with the other pairs.

Tips for tuning a mandolin

  • Tune each string on its own. Two strings played together give an unsteady reading.
  • When both strings of a pair are in tune, play them together: a slow “wobble” in the sound means one of them is still slightly off.
  • Tune up to the note: if a string is sharp, loosen it a little below the note and bring it back up.
  • Without a microphone, tap a note button under the menu to hear its reference tone and tune by ear.
