In Open G the open strings make a G major chord: D G D G B D. Three strings drop a whole step from standard, the 6th, 5th, and 1st, and the other three stay put.

A straight finger across any fret plays a major chord, which makes Open G a favorite for slide guitar, blues, and rock rhythm parts. Keith Richards plays it on five strings, with the low D removed.
