I looked at several sites and I found this:
4 x 2 4 0 0
The 6th string is played on the 4th fret, correct? I found this on a message board but on the sites that I usually go to they don't show this. So is this correct? How can you tell?
That is perfectly acceptable.
When I play acoustic, I think of it as a D/F# capo'd up 2, where it's played 4 2 2 4 5 4, thumb grabbing the G# on the 6th string. Sometimes play standard and try to catch it with the pinky 4 2 2 1 0 0, but that's a little bit of a stretch.
Electric, I'm playing it with a bassist and keyboard player, so much of the time I don't bother. Bassist is playing the G#, so I just play a standard E barre chord. When I do play it. I play it by barring the 2nd 3rd and 4th strings with my index finger and holding the low note with my ring finger. x 9 7 7 7 x. Kinda a reverse A-shape barre.
This is a first inversion E major chord, i.e. with a G# root. An E major chord (triad) contains the notes E, G# and B. That means that any E major shape or partial shape (from CAGED) with a convenient G# root works. Here's a fretboard diagram showing E major chord tones with G# on the bass strings in red:
This is a map of the territory. You should immediately see some voicing opportunities, including:
[ 4 x 2 4 0 0 ] [ 4 x 2 4 5 0 ] [ 4 x x 4 5 4 ]
[ x 11 9 9 9 x ] [ x 11 9 9 12 x ]
[ 4 7 6 4 5 4 ] [ x x 6 4 5 4 ] [ x x 6 4 5 7 ]
also, given that the G# root usually implies chromatic or diatonic root movement, consider the voicing you're moving towards when deciding what to play.
