Answer:
The four most commonly used instruments in the string family are the violin, the viola, the cello and the double (string) bass. They are all made by gluing pieces of wood together to form a hollow sound box. The quality of sound of one of these instruments depends on its shape, the wood it is made from, the thickness of both the top and back, and the varnish that coats its outside surface.
Four strings made of gut, synthetics, or steel are wrapped around pegs at one end of the instrument, tightly stretched across a bridge, and attached to a tailpiece at the other end. The pegs are used to tune the instrument (change the length of the string until it makes exactly the right sound). The strings are tuned in perfect fifths from each other 5 notes apart.
The player makes the strings vibrate by plucking them, striking them, strumming them, or, most frequently, by drawing a bow across them. The bow is made of wood and horsehair. The instrument sounds different notes when the performer presses a finger down on the strings on the instrument?s neck, changing the length of the portion of the string that vibrates. The shorter the vibrating part of the string, the higher the sound produced.
