Tune to E B E G-sharp B E so the open strings form an E major chord. The full browser tuner below starts in Open E mode.
Open E produces a bright, direct E major sound for slide guitar, open-chord riffs, and sustained accompaniment. It uses the same interval layout and fingerings as Open D, shifted upward by a whole step, but it reaches that layout by increasing the pitch of several strings.
The fifth, fourth, and third strings rise above standard tuning, which increases total tension. Raise them slowly in small steps and stop if a string feels unusually tight. On a delicate, older, or lightly built instrument, Open D with a capo at the second fret provides the same sounding pitches and shapes with less added tension.
Confirm the target before tightening any string, especially G#3 on the third string. Alternate among the raised strings rather than bringing one all the way up while the others remain at standard pitch.
The sixth, fourth, and first strings should be E notes in three octaves. The fifth and second strings should be B2 and B3. After those pairs agree, add G#3 on the third string; a gentle open strum should produce a stable E major chord without obvious pulsing.
The open strings contain only E, B, and G#, the root, fifth, and major third of E. A straight barre keeps those intervals intact at higher frets, making major-chord movement and slide intonation visually simple.
