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.
