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.
Twelve-string guitar
The 12-string guitar's greater number of strings and higher cumulative string tension complicates playing, in both hands. Fretting chords requires greater force, and the width of the neck and the added string tension combine to make soloing and string-bending challenging. The gap between the dual-string courses is usually narrower than that between the single-string courses of a conventional six-string guitar, so more precision is required with the pick or fingertip when not simply strumming chords. Consequently, the instrument is most commonly used for accompaniment, though several players have taken the time to develop the 12-string guitar as a solo instrument. Flat-picking solos are more frequently seen with electric players, whereas a few acoustic players, such as Leo Kottke, have adapted fingerstyle techniques to the instrument; players such as Ralph Towner have applied classical playing techniques.
