How to use this tuner
Click Start Tuning and allow microphone access. Play a note, the tuner detects pitch in real time and shows how sharp or flat you are in cents.
The bar spans −50 to +50 cents. Zero is perfectly in tune. The history line shows where you’ve been, useful for spotting whether certain registers consistently drift sharp or flat.
Clarinet (A) is already selected, note names match your written part. When you play a written C, the tuner shows A: correct for your part, a minor third below concert pitch.
Default is A440. Tap + / − to match your ensemble, A441–442 is common in orchestras, A415 for historical pitch.
The A clarinet transposes a minor third below written pitch: when you play a written C, the concert pitch is A. Orchestral composers chose A clarinet for pieces in sharp keys, A, E, and B major, because the transposition puts the instrument in comfortable fingerings. A piece in A major is simply written in C major for the A clarinet. Switching between Bb and A clarinets mid-performance is common in orchestral playing; because the difference is only a semitone, it’s easy to forget to change the tuner setting. Always check the dropdown when you switch instruments. The A clarinet’s throat tones, the G, Ab, A, and Bb above the staff, behave similarly to the Bb: they tend sharp because fewer fingers on the instrument reduces resistance. The pitch history display helps you track whether these problem notes consistently sit above the line across a passage, giving you objective data rather than guesswork.
