Take every song you know in open position and learn it with all barre chords.
OK, but why? What's the benefit or advantage to playing things as barre chords?
If you know 3 you can use them all over the neck not just the first 3 frets example :
your standard E Bar chord shape for F = 133211, by moving it fret for fret down the neck you are playing that chord, F F# G G# A and so on, or for an easy way just play the first and 3rd fingers on E and A string. this will work up and down the neck and are called Root 5th Bar chords, they work best on strings 4,5,and6
I found this FREE PDF down load of Barre chords http://www.guitar-skill-builder.com/Bar … Chart.html
Ok and to answer your question of why? Well once you migrate out of folk,, and even w/ in it, and with your Beatles, conservation of movement and, quite frankly,, the other name for them is POWER CHORDS. You can get much more thump out of them, palm muting is easier, and shifting between chords is quicker. EX going from C D E isn’t that hard open but lacks a certain growl. If you play them as a 2 or 3 finger power chord, you’re just sliding the fingers right up the neck in a smooth progression and able to swap back and forth quickly. Best example I can think of that is not a metal song (as it was written LOLLOL ) would be most of the very popular stuff by THE KINKS. All day and all night and You really got me ( which have been covered by Van Halen and heavier groups) here listen and watch how they are played by everyones favorite Justin guitar.
