My intonation is all over the place: how do I improve it?

Good intonation means playing each note right in tune, neither sharp nor flat. It improves with two kinds of practice: hearing the reference and holding a note while watching a needle. The app does both through the microphone, for free.

Why notes come out of tune

Practice in 3 steps

  1. Tune your instrument with the app's tuner before practicing.
  2. Long notes: hold a note while watching the needle and try to keep it still in the middle. The app measures how long the note stays steady.
  3. Play a scale or song slowly with the microphone on: for each note the app shows whether it's sharp or flat and what to adjust.

Frequently asked questions

How far off is acceptable?

On the tuner, staying within about 5 to 10 cents of the center already sounds in tune to most listeners. The app's exercises accept that range.

Does vibrato affect the reading?

A light vibrato doesn't. A very wide one makes the needle swing: to train intonation, play without vibrato first.

Is a phone tuner reliable?

For practice, yes, in a quiet room with the phone about 30 to 50 cm (1 to 1.5 ft) from the instrument.
