Feedback on Violin Tuner
Violin Tuner
Press Start and bow or pluck one open string close to the microphone. Tune the A first, usually to A = 440 Hz (some orchestras use 442: change it under Reference pitch), then D, G and E. Use the fine tuners for small changes and the pegs only when a string is far off.
Sound is analysed on your device; nothing is recorded or uploaded.

Frequently asked questions
What are the violin string notes?
G3, D4, A4 and E5, from the lowest (thickest) string, each a perfect fifth apart. The A string is tuned first because orchestras tune to an A.
Should I use the pegs or the fine tuners?
Use the fine tuners at the tailpiece for anything less than about a quarter tone off. Turn a peg only when a string is badly out, pushing it gently into the pegbox as you turn so it holds.
What pitch do orchestras tune to?
Most use A = 440 Hz; many in Europe use 442 or 443 Hz, and Baroque groups often use 415 Hz. Set the reference pitch to match your group.
Is my audio recorded or uploaded?
No. The tuner analyses the sound from your microphone in your browser, a few times a second, and throws it away. Nothing is recorded, saved or sent to a server.
Why does the tuner jump between notes?
Usually because more than one string is ringing, the room is noisy, or the note has faded. Mute the other strings with your fretting hand, pluck firmly, and read the needle while the note is still strong. Moving closer to the microphone helps on laptops.
