  • How to use the online guitar tuner

    Guitar tuner instructions:

    • Requirement – You need to install Adobe Flash Player 10.1 or later.
    • Select input source – To be able to tune your instrument you need to allow access to your computer’s microphone. Press the “Allow-button” ( Allow-button from Adobe Flash Player ) in the pop-up window to use the built-in microphone. No audio data is stored or sent to server, for more information see our privacy policy. If the computer does not have a built-in microphone you can use an external microphone, click the settings-button ( Microphone settings ) on the tuner and change the input source to your external microphone. You can also change the input source to line-in, which enables you to plug in an electric guitar to the sound card. Don’t hesitate to contact us if you experience any problems.
    • Pluck the string – The tuner will display the current note and indicate the current pitch.
    • Start to tune – The string is in tune when the needle has a vertical position. If the needle is to the left of the center you need to tighten the string. If the needle is to the right of the center you need to reduce the tension of the string. Remember only to make minor changes to the strings tension while tuning.
    • Start playing – Start playing and tell your friends about this free guitar tuner site.
    • Video instructions:

  • Technical data

    Guitar tuner data:

    • Chromatic: This means you are able to tune all tones of the chromatic scale.
    • Interactive: The tuner will analyze the sound from your guitar and give you instructions in real-time online.
    • Automatic: The tuner detects the pitch automatically and you do not need to choose a specific note.
    • Accuracy: +/- 1 cent of a semitone, i.e. accurate as a conventional hardware tuner.

    The chromatic scale:

    C      C♯/D♭      D      D♯/E♭      E      F      F♯/G♭      G      G♯/A♭      A      A♯/B♭   B

    The guitar tuner never displays flat signs. But do not worry, the reason is very simple. As you can see in the chromatic scale above all twelve semitones can be found. For example, both C♯ and D♭ have exactly the same pitch but they have different names depending on the reference scale. Note that all notes in the chromatic scale with a sharp sign (♯) also have a corresponding note with a flat sign (♭).
