Barre Chord

In music, a barre chord (also known as bar chord or rarely barr chord) is a type of guitar chord, where one or more fingers are used to press down multiple strings across the guitar fingerboard (like a bar pressing down the strings), enabling the guitarist to play a chord not restricted by the tones of the guitar's open strings. Barre chords are often referred to as "moveable" chords, as the whole hand may easily be moved up and down the neck, "in one movement". Commonly used in most popular and classical music, they are frequently used in combination with "open" or standard guitar chords.

Though slightly affecting tone quality, fretting a chord transposes, or raises, the chord a number of half-steps higher, similar to the use of a capo.
