Instrument Tuner
Pick your instrument, then either tune it with the microphone or listen to each string's reference pitch. Everything happens inside your browser — no audio is uploaded anywhere.
Step 1 — Choose your instrument
Press Start, then play one string at a time. The tuner snaps to the closest string on your Violin and tells you whether it is sharp or flat, in cents. Works with any speakers — it listens rather than plays.
Target strings — Violin (4 strings)
These are the notes each string should reach. The tuner highlights whichever one you are closest to. Click a row to lock onto one string; click the same row again to go back to automatic.
Automatic — the tuner picks the closest string.
Click a string to hear its reference pitch and tune by ear. Click the same string again to stop it.
