Suitable for Acoustic / Classical Guitar

A capo (short for capodastro, capo tasto or capotasto, Italian for "head of fretboard" is a device a musician uses on the neck of a stringed (typically fretted) instrument to transpose and shorten the playable length of the strings—hence raising the pitch. It is a common tool for players of guitars, mandolins, mandolas, banjos, ukuleles and bouzoukis. The word derives from the Italian capotasto, which means the nut of a stringed instrument.
