Open G Tuning

–
Ready when you are

The tuner listens through your microphone.

    Choose a tuning

      Strum the open strings and you hear a G major chord — the classic sound of slide guitar and Stones riffs.

      Press Start tuning, pluck a string and turn its peg until the needle is centred and green. The tuner already knows the Open G notes, so it tells you which string you are tuning.

      About Open G

      Open G — D G D G B D — makes the open strings sound a G major chord. The 6th, 5th and 1st strings are each lowered a whole step from standard, and any major chord can then be played by laying one finger across a fret.

      It is a classic for slide guitar and blues, and Keith Richards famously built many Rolling Stones riffs on it, often with the low 6th string removed.

      Tips

      • From standard: lower the 6th string E → D, the 5th string A → G and the 1st string E → D.
      • Bar the 5th fret for C and the 7th fret for D — the three chords behind countless songs.
