Violin, bowed stringed instrument, the highest pitched member of the violin family. The main parts of the violin are the front, also called the belly, top, or soundboard, usually made of well-seasoned spruce; the back, usually made of well-seasoned maple; and the ribs, neck, fingerboard, pegbox, scroll, bridge, tailpiece, and f-holes, or soundholes (see illustration). The front, back, and ribs are joined together to form a hollow sound box. The sound box contains the sound post, a thin, dowel-like stick of wood wedged inside underneath the right side of the bridge and connecting the front and back of the violin; and the bass-bar, a long strip of wood glued to the inside of the front under the left side of the bridge. The sound post and bass-bar are important for the transmission of sound, and they also give additional support to the construction. The strings are fastened to the tailpiece, rest on the bridge, are suspended over the fingerboard, and run to the pegbox, where they are attached to tuning pegs that can be turned to change the pitch of the string. The player makes different pitches by placing the left-hand fingers on the string and pressing against the fingerboard. The strings are set in vibration and produce sound when the player draws the bow across them at a right angle near the bridge.
