42 tunings with step-by-step changes from standard, a mic tuner, reference tones, and a custom tuning builder.
Open E tuning is E B E G♯ B E, from the lowest (6th) string to the highest (1st). Compared with standard tuning, 3 strings change.
The open strings play an E major chord. Bright and loud, a slide guitar favourite; three strings are tuned up, so go gently.
The open strings ring E.

Strum all the strings open, then lay one finger straight across every string. Open: E. At fret 5: A. At fret 7: B. At fret 12: E. Those are the I, IV and V chords of the key, enough for a blues or a folk song.
Open tunings are the classic choice for slide: hold the slide straight over a fret line and every string rings the chord.
Starting from standard tuning: 5th string up a whole step (2 semitones) to B; 4th string up a whole step (2 semitones) to E; 3rd string up a half step (1 semitone) to G#. Use the tuner at the top of this page for each changed string.
From the lowest string to the highest: E2, B2, E3, G#3, B3, E4 (E B E G# B E).
Reverse the changes: 5th string down a whole step (2 semitones) to A; 4th string down a whole step (2 semitones) to D; 3rd string down a half step (1 semitone) to G.
No. The changes are small enough for a normal string set.
