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.
Baryton
The baryton differs from the bass viol in having an additional set of wire strings. These perform two functions: they vibrate sympathetically with the bowed strings, enriching the tone, and they can also be plucked by the left thumb of the performer, creating a contrasting tonal quality. As can be seen in the illustration, the bowed strings are placed on the right, where they can be easily fingered by the player's left hand. The plucked strings are on the left; they are reachable by the player's thumb from the rear, where the back of the instrument's neck is left open.
