Tuning your clarinet
To tune your clarinet using this online tuner, here's what to do:
- With this tuner, click start.
- Click on "allow dacapoalcoda.com to use your microphone".
- Choose the reference A (440Hz, or generally 442Hz).
- Play the note you're tuning to (an A).
- Check the accuracy of the tuning:

The cursor is in the middle: you're perfectly in tune!

The cursor is to the left: you're too low, you need to push the barrel.

The cursor is to the right: you're too high, you need to pull the barrel.
Too high: I pull the barrel (the tube becomes longer, so it sounds lower).
Too low: I push the barrel (the tube becomes shorter, so it sounds higher).
Before orchestra rehearsals, all woodwinds in the wind instrument family tune to an A, so it's best to get used to tuning to an A, even if you're playing alone.

Tune your clarinet to an A (A4), by pulling or pushing the barrel.
