Major 7 Voicings in 4ths and 5ths with Crunches by BarryK
I don't know if this is covered elsewhere, but I found a couple of major 7th voicings with crunches (two notes next to each other) in the middle. They are based on two 4ths, or 5ths next to each other. I found the one with 5ths in "I'll Remember April" at the end of the B section.
Examples of Emaj7
4ths: B D# E G# - Sticking B & E left hand 4ths, D# G# right hand 4ths; Leading tone is 3rd of the chord.
5ths: G# D# E B - Sticking G# & D# left hand 5ths, E B right hand 5ths; Leading tone is 5th of the chord.
where 1 = outer left, 2 = inner left, 3 = inner right, 4 = outer right
