How to practise with a drone

  1. Choose the tonic of the scale you're practising.
  2. Play the scale slowly and listen to each interval against the drone.
  3. If you hear 'beating' (the sound wobbles), you're out of tune: adjust until it disappears.

To measure which notes you play sharp or flat, try the Intonation X-ray.

Can I change the pitch?

Yes. Set the reference A (e.g. 442 or 415) or choose a historical pitch.

Does it play in the background?

While the page is open, yes. Some phones stop it when the screen turns off.
