The optimal positioning of the right and left hand is achieved through compliance with the ergonomic principles outlined in previous post. The hand must be tilted on the ulnar side to an angle of 15 degrees at the wrist. A slight flexion toward the outside of 15 degrees at the wrist completes the positioning. Although it is impossible to maintain this optimum positioning at all times, the player will attempt to return to this position in which the fingers are free to move as often as possible.
