42 tunings with step-by-step changes from standard, a mic tuner, reference tones, and a custom tuning builder.
Open G tuning is D G D G B D, from the lowest (6th) string to the highest (1st). Compared with standard tuning, 3 strings change.
The open strings play a G major chord. A classic for slide guitar, blues and rock rhythm parts.
The open strings ring G (with D as the lowest note).
| String | Note | Frequency (A = 440 Hz) | Change |
|---|---|---|---|
| 1st (highest) | D4 | 293.66 Hz | -2 from E |
| 2nd | B3 | 246.94 Hz | as standard |
| 3rd | G3 | 196.00 Hz | as standard |

Strum all the strings open, then lay one finger straight across every string. Open: G. At fret 5: C. At fret 7: D. At fret 12: G. Those are the I, IV and V chords of the key, enough for a blues or a folk song.
Open tunings are the classic choice for slide: hold the slide straight over a fret line and every string rings the chord.
Starting from standard tuning: 6th string down a whole step (2 semitones) to D; 5th string down a whole step (2 semitones) to G; 1st string down a whole step (2 semitones) to D. Use the tuner at the top of this page for each changed string.
From the lowest string to the highest: D2, G2, D3, G3, B3, D4 (D G D G B D).
Reverse the changes: 6th string up a whole step (2 semitones) to E; 5th string up a whole step (2 semitones) to A; 1st string up a whole step (2 semitones) to E.
No. The changes are small enough for a normal string set.
