The notes are E G# B, and D# for the maj7, so in sequence 12 11 9 8 x x. For E7 chords please see the discussion at
http://www.thefretboard.co.uk/discussion/610/chord-of-the-week-10-8-13-e-e7.
Usual open position voicings:
E: 022100
Emaj7: 02110(0)
The Emaj7 sounds a bit weird in many contexts with the high E ringing a b9 interval above the D# on string 4, so I prefer
Emaj7: 022444 or 022440.
There are some pleasant sounding Emaj7 chords higher up the neck using the open strings ringing, e.g
Emaj7: 076800
Emaj9: 076870 (nice harp-scale fragment of D# E F# available on strings 3 1 2)
What are your favourite Emaj7 and E chords and extensions?
@Bucket, I think your 'Eb' chord goes here!
