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.

A# Whole Tone in Open E — Notes and Intervals

The A# Whole Tone scale, also known as Messiaen's Mode of Limited Transposition #1, is a perfectly symmetrical scale that lacks a tonal center, creating a sense of weightlessness and blur. On Guitar, it contains the notes A#, C, D, E, E##, F###. It divides the octave into six equal whole steps, meaning only two unique whole tone scales exist. Popularized by Claude Debussy and used extensively in film scores, it evokes impressionistic, dreamlike atmospheres where no single note feels like home. Use it over augmented triads and 7#5 chords for a floating, surreal effect. Commonly used in Impressionist, Film Scores, Jazz, Ambient, Experimental. Notable players include Claude Debussy, Thelonious Monk, Wayne Shorter, Joe Satriani. Use over augmented triads, 7#5 chords. Perfect for dream sequences, transitions, and any moment where tonality should dissolve.

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.
