barre chord
A guitar chord where one finger presses across all or several strings simultaneously.
In Depth
Barre chords are moveable chord shapes that allow guitarists to play any chord using the same finger pattern shifted up or down the neck. The index finger acts as a moveable nut, barring across the strings while the remaining fingers form the chord shape. Mastering barre chords is a crucial milestone for guitarists, transforming them from players limited to open-position chords to musicians who can play in any key.
The F major barre chord is often called the beginner killer; it is the single chord most responsible for guitarists giving up in their first year of learning.
