Barre chords
A barre chord uses your index finger to press several strings at once, acting like a movable nut. Learn two shapes and you can play any major or minor chord anywhere on the neck.

The two shapes that cover everything
The E shape puts the root on the low E string (F is the E shape at fret 1). The A shape puts the root on the A string (Bm is the A-minor shape at fret 2). Slide either shape up the neck and the chord name follows the root note under your index finger.
Getting every string to ring
Roll your index finger slightly onto its bony side, keep your thumb low behind the neck, and pull back gently with your arm instead of squeezing harder. Check each string one at a time and adjust until none buzz.
Shortcuts while you practice
Every chord page lists easier options, such as a capo plus an open shape, so you can keep playing songs while your barre chords improve.
Questions
Why are barre chords so hard?
One finger has to hold down several strings evenly. It takes a few weeks of short daily practice for the hand to build the strength and the right finger angle.
Which barre chord should I learn first?
F (E shape at fret 1) and Bm (A-minor shape at fret 2). They appear in many songs and teach both shapes.
