How to Hold a Pick:
Hold it with your thumb and pointer finger.
Notice that if my thumb is horizontal, the pick is pointing straight down at the floor, at a 90 degree angle.
It’s like holding a key when you’re going to unlock a door.
Picking begins in the wrist, as an up and down movement.
Try picking up and down on one of your strings (known as alternate picking).
When you strum chords, the movement still begins in the wrist, and the elbow follows.
