The violin, sometimes known as a fiddle, is a wooden chordophone (string
instrument) in the violin family; most violins have a hollow wooden
body. It is the smallest and thus highest-pitched instrument in the
family. The violin typically has four strings, usually tuned in perfect
fifths with notes G3, D4, A4, E5, and is most commonly played by drawing
a bow across its strings.
Apart from the standard, full (4⁄4) size, violins are also made in
so-called fractional sizes of 7⁄8, 3⁄4, 1⁄2, 1⁄4, 1⁄8, 1⁄10, 1⁄16, 1⁄32
and even 1⁄64. These smaller instruments are commonly used by young
players, whose fingers are not long enough to reach the correct
positions on full-sized instruments.
