Flute Tuner

Tune your flute or piccolo with your microphone. The flute plays at concert pitch, so the note you see is the note that sounds.

Tuning with the headjoint

You tune a flute by sliding the headjoint in or out of the body. Warm up, then play a steady, relaxed note.

  • Needle left (flat): push the headjoint in.
  • Needle right (sharp): pull the headjoint out a few millimetres.

Your embouchure (the shape of your lips) matters too. Rolling the flute in lowers the pitch and rolling it out raises it, so keep your usual position while tuning.

Why use it

The flute plays at concert pitch. Small changes in your breath and embouchure change the pitch, so seeing it on screen helps you hold notes steady.

How to use it

Press Start tuning and play a relaxed, steady note. Slide the headjoint in if the needle is on the left, or out if it is on the right.

Frequently asked questions

Is the flute a transposing instrument?

No. The concert flute sounds the note that is written. The piccolo sounds an octave higher than written but uses the same note names, so the concert pitch setting works for both.

What note should I tune a flute to?

Orchestras tune to A, and bands often tune to B♭. Many flutists check both a low note and a note in the middle range.

Why is my flute sharp when I play loudly?

Blowing harder raises the pitch on the flute. Practise keeping the needle in the centre while you play loud and soft.
