sauvignon1: My parents got me a guitar for Christmas two years ago. I wish I could play it seriously, but there's one problem: my fingers are too short. I can't play barre chords, which dooms me to playing nothing but open chords. If I encounter a song that calls for barre chords, tough shit. Oh well, at least the guitar looks cool in my room.
My fingers are too short, and I can play barre chords; it just took me ten times longer to get it down, and there are still some I have trouble with, but I'm getting better. Also, don't do what I did and suffer from "Jimi Pagitis"! That is the uncontrollable urge to sling your axe as low as you can possible get it. It may look stupid to jack it way high up but thats how Angus Young and Vernon Reed play and they are rock legends. When you start to get good...which takes hours and hours and hours and hours (start at 4 or 5 a day minimum) of practice, you wont care how goofy you look because people will be in awe of your deadly riffs.
Also what kind of guitar is it? What kind of amp? A piece of shit may not pick up the barre chord even if you are playing it correctly.
