Violin Tuner

Tune your violin's G-D-A-E strings by microphone and keep your fifths clean. No install, no account, free in your browser.

Allow the microphone and play a string to start tuning.

How the violin tuner works

An online violin tuner reads the pitch of a string, bowed or plucked, through the microphone and shows how far it sits from the target note in cents. It tracks the high E as steadily as the low G, so all four strings tune with confidence. Allow the microphone, play a string and turn the fine tuner or the peg until the needle centers.

A violin is tuned in fifths (G D A E); when each string forms a clean fifth with the one before it, the instrument rings in balance. Use the fine tuners for small adjustments and the pegs for bigger moves; before a rehearsal this balance brings the strings onto one shared reference.

String notes and frequencies

The tuner is chromatic — find your target note here, then turn the peg until the needle centres on it. Frequencies are given against A4 = 440 Hz.

Calendar & Poll

Get everyone in the same room

Your strings are tuned. The real trick is getting everyone to the same rehearsal: with BandUp's date poll the band votes on a day, and once it locks the rehearsal drops onto the shared calendar so nobody chases dates.
