Watch the F Minor Maj7#11 online guitar lesson by Brad Carlton from Guitar Lab: Open String Universe
This chord voicing is achieved by moving the lowest four voices of the open Em form up 1 fret. The first and second strings(voices) remain open and thus extend and/or alter the basic minor chord which is always occuring in voices 6 through 3.
The voicing for this chord is as follows(from low to high in pitch):
6th string(voice) 1
5th string(voice) 5
4th string(voice) 1
3rd string(voice) b3
2nd string(voice) #4(b5, #11)
1st string(voice) 7
Analyzing this chord against the 6th voice (as the root) reveals the name as Fminor maj7#11.
The applicable scale(s) for soloing over this chord would be:
F whole-half diminished
1 2 b3 4 b5 #5 6 7
F G Ab Bb Cb C# D E
Notice that the whole-half diminished scale does not contain a natural 5 which is occuring in voice 5 of the chord.
