  • 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 (♭).
