Strings (tennis)
In tennis, the strings are the part of a tennis racquet which make contact with the ball. The strings form a woven network inside the head (or "hoop") of the racquet. Strings have been made with a variety of materials and possess varying properties that have been measured, such as dynamic stiffness, tension retention, thickness (gauge), string texture (shape of the string), and rebound efficiency.

The larger of the two strings (the "male" string) has 130 hairs from a stallion's tail, while the "female" string has 105 hairs from a mare's tail. Nowadays the strings are made of nylon. Traditionally, the strings were tuned a fifth apart, though in modern music they are more often tuned a fourth apart, usually to B-flat and F. The strings are stopped either by pinching them in the joints of the index and middle fingers, or by pinching them between the nail of the little finger and the pad of the ring finger.
