On the guitar you play a with a grip (also called a chord shape): the shape your fretting hand makes on the neck, with each finger pressing a string at a . This page shows the most important grips and how they connect.
Each grip is drawn as a chord diagram, a small picture of the neck:
The first chords most guitarists learn are open chords: grips at the end of the neck that let some strings ring open. They're easy to hold and ring out nicely. Press play to strum each one.
Open chords only exist for a few chords. A barre chord moves an open shape up the neck: your index finger lies flat across the strings and takes the place of the nut, the white strip at the end of the neck where the open strings stop.
To free your index finger, play the E shape with fingers 2, 3 and 4 instead of 1, 2 and 3. Then slide it up: each fret is a , so the E shape becomes F at the 1st fret, F♯ at the 2nd and so on. The A shape works the same way with its root on the A string. Its barre covers five strings, and the low E string isn't played.
The open C, A, G, E and D chords can all be moved up the neck as barre shapes. That's where the name CAGED comes from. Played for the same chord, the five shapes join up along the neck like puzzle pieces, so you can play any major chord in five places.
Going up the neck from the open C chord: A shape at fret 3, G shape at fret 5, E shape at fret 8, D shape at fret 10, and the C shape again at fret 12. Here is C major in all five, in that order:
The fretboard tool shows the open and CAGED grips for any major or minor chord (Chords → Fingering), and how the CAGED shapes connect.
