*The violin is a wooden string instrument in the violin family. It is the smallest and highest-pitched instrument in the family in regular use.
*A violin is tuned in fifths, in the notes G3, D4, A4, E5
*A violin generally consists of a spruce top, maple ribs and back, two endblocks, a neck, a bridge, a soundpost, four strings, and various fittings, optionally including a chinrest, which may attach directly over, or to the left of, the tailpiece. A distinctive feature of a violin body is its hourglass-like shape and the arching of its top and back.
*Strings were first made of sheep gut , or simply gut, which was stretched, dried, and twisted. In the early years of the 20th century, strings were made of either gut, silk, aluminum, or steel.
*A violin is usually played using a bow consisting of a stick with a ribbon of horsehair strung between the tip and frog (or nut, or heel) at opposite ends. A typical violin bow may be 75 cm (30 in) overall, and weigh about 60 g (2.1 oz). The hair of the bow traditionally comes from the tail of a grey male horse (which has predominantly white hair), though some cheaper bows use synthetic fiber.
