Wrist Motion
The wrist is probably the most commonly used joint in picking technique. Thanks to its 360-degree range of motion, it is capable of creating all pickstroke types: single escape, double escape, and trapped.
The wrist is also frequently used in combination with other joints, like the elbow and the forearm, to create motion paths that neither the wrist or any of these joints can create individually. For example, wrist-forearm combinations are common in musical styles like bluegrass, where the elbow is often used for projection on acoustic instruments, but can’t generate the double escape picking motion needed for classic bluegrass technique like the forward roll.
