Violin
strings were first made of sheep's intestines. This material was known
more specifically as "catgut." It was stretched, dried, and
twisted into a usable shape. The name is a little misleading as the
instruments were never created from internal cat parts.
There are four violin strings. They are G, D, A, and E. They are attached
to the base via a tailpiece. From there, they run up across a wooden
bridge toward neck of the instrument. They run parallel to the fingerboard
and are connected to the top of the instrument by a pegbox.
Violin strings today will more commonly have either a synthetic or
steel core. The former types are usually stranded and wound with various
metals. Steel cores may be solid or stranded. They will also be wound
with various other types of metals.
