TuneHow to tune a clarinet
- Press Start Tuning and allow microphone access when your browser asks.
- Play one note. Play one long, steady note, close to the microphone, and let it ring.
- Read the display. The big letter is the nearest note. The bar shows how far off you are: left is flat (tune up), right is sharp (tune down).
- Turn until it goes green. Inside your tolerance (±3 cents by default) the display turns green and the string gets a check mark.
Tips
- Tune open G and throat B♭ first, then check clarion B and C.
- Pull the barrel to go flatter; push in to go sharper.
- Keep the reed and mouthpiece warm; tune after playing for a minute.
FAQ
Does this clarinet tuner show written or concert pitch?
It shows the written note for a B♭ clarinet by default, so it matches the music you read. Choose “Concert pitch (C)” under Settings to see sounding pitch.
Why am I sharp at the start and flat later?
Instruments warm up as you play. Tune after a few minutes of playing, and check again during long rehearsals.
Can I tune to A = 442 Hz?
Yes. Open Settings and set Reference A4 to 442, or any value from 400 to 480 Hz.
