Barre chords.

Hello again. At my previous post i promised you to tell about barre chords. So here they are:
Barre chords are a type of guitar chords, where one or more fingers are used to press down
multiple strings across the guitar fingerboard. Name of those chords comes from a French word barre, witch in English is bar. Bar, because the first finger shape is like bar over the entire fret.Barre chords’ primary purpose is to shift any of the open string chords an arbitrary number of half steps up the neck of the guitar; similar to the use of a capo.
Basically the barre chords are divided into two types: E shape and A shape. The name comes from the name of the open chords. E shape because besides your first finger, all the other fingers are shape like an open E, and the same thing for A shape barre chords. To change chord just move up or down on the fretboard like you do on power chord.
