BARRE CHORDS for GUITAR
Having mastered the basic fifteen open beginners chords, the next step is to master Barre chords on the guitar.
Learning even the simplest shapes will increase your basic 15 up to over 150 chord combinations of progressions.
As the name suggests your index finger acting like a”bar”replaces the nut, by putting your finger across all 6 strings
you are allowing any open chord to be played anywhere you wish on the fingerboard.
The secret to the  success  of playing Barre chord is realising that it is a movable shape and can be played up and down
the fingerboard as you wish.
By not changing your finger positions at all it can give you a choice of approximately 12 different chord positions.
The name of the chord  depends on the position of the finger placed on the neck to determine the name.
The most common shapes usable would be the E shape which is based on the open E major chord, the C shape is based on
the open C major chord also the A shape is based on the A major chord.
The A and E shape can without too much practice be adapted to give minor, seventh, minor seventh and major seventh chords
