Edited to Add:  Try to learn to form your "first position" open chords without using your index finger also. the A,D, E, G, C, and minor shapes are mobile up the neck with the addition of the "index finger Barre" and it might make transitions into and out of Barred forms easier down the road.

Without paying close enough attention, I misposted this to a barre thread. Sorry folks!!!

Good advice anyway.

I think it's still good advice though! 

edited for spelling - ahh!

There are a bunch of videos on Youtube with hints about barre chords.  I'd suggest watching a few of them and take the bits that make sense to you given your hand, your guitar, and your interests.  Then practice, practice, practice. 

For what it's worth, everyone who has ever played guitar has had trouble with barre chords.  Even Russell.  Until they practiced enough to learn how to do them.

1. Make sure your guitar is set up correctly and action is low enough that you don't have to do a ton of work.
2. Make sure your guitar neck is in a high enough position to allow your hand to hang from your elbow. Prop your left knee up or use a strap, even when sitting. This is good position: https://deftdigits.com/blog/wp-content/ … osture.jpg  This is bad position: http://www.fretjam.com/images/acoustic- … itting.jpg Also make sure your guitar isn't angled upward toward you. This makes it easier to see the fretboard but much harder to play, i.e. http://takelessons.com/blog/wp-content/ … 06/117.png
3. When you fret a barre chord (or any note for that matter) the pressure doesn't go directly in to the fret board. Your elbow pulls your hand both back and down slightly. So you are using gravity, not hand strength, to fret notes.

Hope this helps!
