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.
Notable artists: Keith Richards, Robert Johnson, Ry Cooder, Joni Mitchell, The Black Crowes
Best for: Slide guitar, delta blues, Keith Richards-style rock riffs, and open-string fingerpicking
