Tune your banjo with the microphone of your phone or computer. The 5-string preset (open G) is already selected. For a 4-string tenor banjo, pick “Banjo (CGDA)” in the menu.

Many Irish players tune the tenor banjo G D A E (G2 D3 A3 E4), one octave below the fiddle. The tuner recognises every note, so you can tune to it as well.

How to tune a banjo in 3 steps

  1. Press the microphone button and allow microphone access when your browser asks.
  2. Pick one open string and let it ring. The tuner shows the note and a needle: left is flat, right is sharp.
  3. Turn the tuning peg until the needle stays in the centre. Repeat for every string.

Tips for tuning a banjo

  • A banjo is loud and its notes fade quickly. Pick again if the reading disappears.
  • Tune up to the note: if a string is sharp, loosen it a little below the note and bring it back up.
  • Check the tuning again after a few minutes: new strings and a change in room temperature both move the pitch.
  • Without a microphone, tap a note button under the menu to hear its reference tone and tune by ear.
