Dobro Tuning (G.B.D.G.B.D)

The dobro is a type of guitar with a metal resonator. It is usually held horizontally on the lap and played with a metal bar that acts like a moveable fret. It is typically tuned to a G major chord that is different from the G major chord of the Open G tuning (DGDGBD), though the three highest strings are identical. Consequently, the high three strings of both tunings can be played the same.

The dobro tuning offers two triplets of strings tuned an octave apart, which makes it easy to visualize chord forms and to transpose them up and down octaves. For instance, the three note A minor chord can be played either high or low, or the two octaves can be combined to form a more complete version.
