    G3: 196.00 Hz — lowest and thickest string.
    D4: 293.66 Hz.
    A4: 440.00 Hz — commonly used as the tuning reference.
    E5: 659.25 Hz — highest and thinnest string.
    How the Violin Tuner works:

    The tuner listens through your microphone and estimates the fundamental frequency of the note being played. That frequency is compared with the nearest musical pitch and the standard violin string frequencies.

    A reading below 0 cents means the note is flat and needs to be raised. A reading above 0 cents means the note is sharp and needs to be lowered. When the reading is close to 0 cents, the string is in tune.

    For the most accurate result, play one open string at a time in a reasonably quiet room.
    Important: Tune violin strings gradually. Large or sudden increases in string tension can cause a string to break. When a string is far below pitch, bring it up slowly while repeatedly checking the tuner.

  • An Online Violin Tuner helps violinists tune their instrument using the microphone on a phone, tablet, or computer. The tuner listens to the pitch of each string and compares it with the standard frequencies used for violin tuning.

    A standard violin is normally tuned to G3, D4, A4, and E5. The G string is the lowest open string at approximately 196 Hz, followed by D4 at 293.66 Hz, A4 at 440 Hz, and E5 at approximately 659.25 Hz.

    Play one open string at a time and allow the note to ring clearly. The tuner displays the detected pitch, frequency, and the number of cents the note is away from the nearest correct pitch.

    A negative cents reading means the string is flat, so the pitch needs to be raised. A positive reading means the string is sharp, so the pitch should be lowered. When the tuner reads close to 0 cents, the string is very close to being in tune.

    For the best results, tune in a relatively quiet room and avoid playing multiple strings at once. Background music, conversations, and other instruments can interfere with pitch detection.

    Tip: When tuning a violin from a pitch that is far too low, raise the string tension gradually. Make small adjustments and repeatedly check the tuner rather than turning the peg quickly, especially with the thinner E string.
