A classical guitar, sometimes also called a Spanish guitar (referring to its origin, not repertoire), is a musical instrument from the family of musical instruments called chordophones. The classical guitar is characterized by nylon strings (the bass strings usually being of nylon wound with a thin metallic "thread") which are plucked by the guitarists fingers. The name classical guitar does not mean that only classical repertoire is performed on it (although classical music is a part of the instrument's core repertoire) - instead all kinds of music (classical, jazz, folk, etc.) can be and are performed on it.
