A Barre Chord (b??ri k??rd) is a type of chord that requires a guitar player to use one finger to press more than one string down at a time. These types of chords are extremely versatile as, by sliding up and down the neck of the guitar while keeping one of a few barre chord hand shapes, they can be used to form different chords easily.

Though not complex in theory, barre chords are tough for beginners because they require maintaining constant pressure over the multiple strings at once. As the strings digging into the untrained unhardened finger can be uncomfortable, some players use metallic finger sleeves for people initially learning barre chords.

A chord (k??rd) is a series of notes that are played at the same time in harmony. More specifically, a chord is a series of three or more notes, usually a combination of at least the first note of a key and the third and fifth note of the same key. A basic chord that consists of those three notes is also known as a triad to music theorists, however chords can also be described as majors, minors diminished or augmented.
