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.

C Lydian in Open G — Notes and Intervals

It is known for its ethereal, dreamlike, and cinematic quality. Because it avoids the pull of the perfect fourth, it is a favorite for film composers wanting to evoke a sense of wonder or otherworldly space. The diatonic chords of C Lydian are CMaj7, D7, Em7, F#m7b5, GMaj7, Am7, Bm7. Commonly used in Film Scores, Progressive Rock, Fusion, Ambient, Dream Pop. Notable players include Joe Satriani, Steve Vai, John Williams, Hans Zimmer. Use over Maj7#11, Maj9 chords. Ideal for non-resolving major passages. Avoid when the music needs to feel grounded or resolved.

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.

The #4 (tritone from root) eliminates the gravitational pull of the perfect 4th, creating a sensation of weightless suspension — the reason film composers use it for 'wonder' and 'awe'.
