What is Open G tuning?

Open G tuning changes the strings to D-G-D-G-B-D (low to high). Strumming all strings open produces a G major chord. Barring any fret gives you a major chord at that position, which is ideal for slide guitar.

What scales work in Open G tuning?

The G major pentatonic and G blues scale are natural fits. For slide playing, the major scale patterns align perfectly with the open tuning. The Mixolydian mode also works beautifully for a bluesy feel.

Why do slide guitarists use Open G?

Open G makes slide guitar much more intuitive. Since barring across all strings at any fret produces a major chord, you can play melodies and chords simply by moving the slide up and down the neck. This is why it's been the standard tuning for blues slide guitar.

About Open G Tuning

Open G tuning (D-G-D-G-B-D) produces a G major chord when strummed open, making it the definitive tuning for slide guitar and delta blues. The tuning's natural consonance means that barring across any fret gives you a major chord, which is why it's been the backbone of blues and roots music for over a century.

From Robert Johnson to Keith Richards, Open G has shaped some of the most iconic music ever recorded. Keith Richards famously removes the low 6th string entirely in this tuning, creating his signature five-string sound on songs like 'Start Me Up' and 'Brown Sugar'. For slide players, Open G is essential — it allows clean, singing slide lines across all strings with minimal effort.
