Paint It Black

Observe the posture and technique that is very accommodating for playing difficult pieces.
 

1. Notice that the guitar is placed on my left leg and my left knee is slightly higher than my hip.

2. Notice the guitar is tipped up at an angle so my left hand can reach the neck easily and my wrist is relatively straight allowing my fingers complete mobility with no stress on the tendons.
 

3. Notice the placement of the right arm over the guitar, it's placed so the hand is positioned right over the strings so you'll see the elbow is not on the top of the guitar and the fingers can extend into the strings or what I refer to as "standing on top of the strings.
