Keep your plucking hand in a relaxed natural position.
~ Right Hand Positioning ~

Just as in the left hand, it is important to keep the wrist of the right hand as straight as possible. The greater the angle of your wrist the greater the friction on the tendons moving back and forth through the joint. Rest your right hand in position on the bass. Don't even think about playing. Do not flatten your palm across the bass strings. Allow the tendons, muscles and elastin (the elastic connective tissue membrane that connects all muscles, tendons and organs) to influence the natural cupping position of your palm. Do not rest too heavily on the body of the bass with the underside of your forearm. Doing so will restrict blood flow and necessitate excessive bending of the wrist in order to reach down for the strings. Such contortions will constrict tendon movement and increase the probability of repetitive motion injury. To avoid this underarm pressure on the bass, you will need to bring your elbow up and slightly forward. This position will also enable you to straighten you wrist. With the hand remaining in this relaxed position, move the entire forearm either up to algin the finger tips with the E string or down to algin the finger tips with the G string. You will notice that your second finger extends further than your first finger. Slightly bend the second joint of the second finger to bring the tip into line with the tip of the first finger (see illustration B below). Now pluck a string by using only the joint at the base of the finger joining the palm. Using primarily the joint of your finger that joins the palm enables you to maintain consistent alignment of the finger tips by not disturbing the flex of the finger joints that help algin the finger tips. Play into and across the string at about a 45 degree angle, resting the stroke on the next string.
