Some good guitar barre chord charts are the E shape and A Shape charts, according to the FretJam and Cyberfret websites. Barre chords are movable along the fret, so guitar players are able to keep the same chord form anywhere along the fret. Basic barre chords are best learned after the guitar student understands basic open position chords and power cord shapes.
The E Shape barre chord chart is formed through the E major open position chord with the high E, low E and B strings covered by the barre, states the FretJam website. The A Shape barre chord is formed through the A major and minor shapes with the D, B and G strings covered by the barre.
