What is capo meaning?

A capo is a device used on the neck of a guitar, mandolin, banjo, or other stringed instrument to shorten the playable length of the strings, hence raising the pitch of the instrument. Capos are commonly used by musicians to change the key of a song by raising the pitch without having to change the fingering of chords. They also allow players to use open chords in different positions along the neck of the instrument. The word "capo" is short for capotasto, which is Italian for "head of the fretboard." Capos come in various designs, including spring-loaded clamp-style capos and screw-style capos that are fastened to the neck of the instrument.
