Watch the Bar Chords online guitar lesson by Matthieu Brandt from Chord Cookbook
Bar chords are next on the menu, with an overview of the three different bar chord shapes. You can use these to form major, minor, dominant seventh, major seventh and minor seventh chords all over the neck of the guitar. The roots of these chords can be found on strings 5 and 6. Your index finger is used to bar the strings within one fret. The shapes you create are all moveable.
