Watch the A Minor add9 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 5 frets. 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) 2(9)
1st string(voice) 5

Analyzing this chord against the 6th voice (as the root) reveals the name as Am add9.
