Mare ear, first off and most importantly, how did you get your user name?!?!

But to your topic, barre chords are undoubtedly the most asked about, complained about, posted about subject from us beginners on forums, not just this one.

And the very tedious answer is "it will come". It has nothing to do with short fingers. I have short fingers and am starting to get barre chords down. Like everyone I struggled with the F Major barre chord at first. And posted and griped about it (primarily on another forum). But now I am hitting it probably 60% of the time cleanly.

My problem du jour is the F7 barre chord. At first I absolutely could not get it no matter how I adjusted my fingers or no matter what faces I made. All of a sudden I went to fret it one day and it sounded ok. I don't know why.

I think it is a combination of finger memory, adjusting until you get the position correct, and finger strength. The latter has to be developed over time.

I'm not sure I agree with Slipin Lizard's limit of two minutes. But he is far more knowledgeable than I. But his point is very well taken. Practice barre chords for a limited amount of time and then go to something fun. Don't get discouraged. Barre chords are also very strenuous and your hand will tire very quickly. I started out working them 10 minutes AT MOST before my hand got sore and tired. I am now where I will work them 15 -20 minutes a day.

They will come! Good luck.
