Clarinet tuner
A free clarinet tuner in your phone's browser: play written G, B and C on a B♭ clarinet (or an A clarinet), see how far off you are in cents. Nothing uploaded.
–✓
The microphone stays open while you tune and closes when you stop, when everything is in tune, or after half a minute of quiet. Nothing is recorded or sent.
How to tune
A B♭ clarinet sounds a whole tone below what it reads, an A clarinet a minor third below. Pick yours, and the tuner names the notes as you read them. Warm up first, then play the open G, the B and the high C long and steady.
Sharp: pull the barrel out a little. Flat: push it in (or, once the barrel is all the way in, a shorter barrel). If only the throat G is sharp, pull out at the middle joint instead.
The needle shows how far you are from the note the tuner expects, in cents: a hundred cents is a semitone, five or closer gets the tick, and anything inside twenty most people don't hear.
Then play something
The notes you tuned go into Brumm as a short melody, inside a club track with a beat and a bass. No account, no upload: the notes travel inside the link itself. Hum or play a line there, and it becomes an instrument.
The microphone is read in the browser and nothing is kept. How the site counts visits.
