What is Open E tuning?

Open E tuning is E-B-E-G#-B-E (low to high). Strumming all strings open produces an E major chord. Barring any fret gives you a major chord at that position, making it ideal for slide guitar.

What is the difference between Open E and Open D?

Open E and Open D have identical interval structures — Open E is simply Open D tuned up one whole step. Open E sounds brighter and has higher string tension. Open D is gentler on the neck and preferred for acoustic guitars. You can achieve Open E sound by using Open D with a capo at the 2nd fret.

Is Open E safe for acoustic guitars?

Open E puts more tension on the neck than standard tuning because three strings are tuned UP. On acoustic guitars, especially older or lighter-built ones, this extra tension can cause damage over time. Many acoustic players use Open D with a capo at fret 2 instead.

C Bebop in Open E — Notes and Intervals

The C Bebop scale is the dominant bebop scale, an eight-note extension of the Mixolydian mode. On Guitar, the notes are C, D, E, F, G, A, Bb, B. By adding a chromatic passing tone, it ensures that the most important notes land on the strong beats, allowing jazz players to create fluid, professional-sounding lines. Commonly used in Jazz, Bebop, Swing, Hard Bop. Notable players include Charlie Parker, Wes Montgomery, Joe Pass, George Benson. Use over dominant 7th chords. The added passing tone ensures that the root, 3rd, 5th, and b7 fall on downbeats during eighth-note runs — the 'trick' that makes bebop sound professional.

About Open E Tuning

Open E tuning (E-B-E-G#-B-E) produces a bright, full E major chord when strummed open. Structurally identical to Open D but tuned a whole step higher, Open E delivers a snappier, more cutting tone that has defined the sound of electric slide guitar in blues-rock and Southern rock.

Duane Allman used Open E on the Allman Brothers Band's legendary 'Statesboro Blues' and 'At Fillmore East' recordings, establishing it as the definitive electric slide tuning. Derek Trucks carries on this tradition as one of the greatest living slide guitarists. The Black Crowes used Open E for 'She Talks to Angels'. Because three strings are tuned UP from standard (the 3rd, 4th, and 5th), Open E puts more tension on the neck than Open D — this is why many acoustic players prefer Open D, while electric players favor Open E for its brighter bite.
