About Open E Tuning

Open E tuning is E B E G# B E (low to high). The open strings spell an E major chord, so barring any single fret produces a complete major chord up and down the neck — the classic recipe for bottleneck slide playing. It is the same interval pattern as Open D, only a whole step higher, which gives it a brighter, more cutting voice at the cost of extra string tension.

To reach Open E from standard EADGBE, you raise three strings: tune the A (fifth) string up a whole step to B, the D (fourth) string up a whole step to E, and the G (third) string up a half step to G#. The low E, B and high E strings stay at their standard pitch. Because you are tuning strings up rather than down, go slowly — the added tension is significant on a steel-string acoustic, and some players prefer Open D to avoid stressing the neck.

The reward is that big, brilliant open E chord that has powered slide blues and roots rock for decades.
