- I cannot for the life of me play chords without creating a dead string by touching neighboring strings. It sounds really twangy when i play and i hate it. I have long nails but a trimmed them really short but i'm still having problems
This is normal at the beginning and is one of harder parts of playing chords at first. If you think about it, the concept of the guitar is very simple: put your fingers at these places and then hit the strings over here with the pick. So why do people have to practice every day for years to get it down? The reason is because exactly where you put your fingers, down the the millimeter, and exactly how they are curled and shaped and every other detail makes a big difference.
The good news is that with enough practice, your hands will develop muscle memory and you won't have to struggle with those millimeter differences, your hands will take care of that for you. You'll think "G" and it will just happen. To get there, you have to practice every day and don't lose hope. The nice thing is there's no magic ingredient to it, nothing special, no inborn talent necessary, just practice every day.
- How do i bar? I looked up a lot of tutorials but when i try it hurts
my fingers and sounds, again, twangy (kinda sitar like??)
This is a lot like the above. First, you do need some strength which comes with time. Second, those millimeter differences in placement can help make it so you need less strength, and that's what really counts. I would keep working on barre (just an alternate spelling) chords, but don't overdo it. Just a few minutes a day working on one or two barre chords for now and stop if your muscles get tired. This is one part of guitar playing so difficult and annoying it can be a problem even for experienced players. I've been playing for almost 20 years and I just started changing the chord shapes and how I finger them so I hardly ever even play barre chords now.
- HOW can i stretch my finger so they reach a little better?? Is there
anything i can do to make my fingers stretch so i can play chords
like a G or an a7??
As Bacs wrote, don't think about trying to make your fingers longer. That only happens as you grow (and you may still grow more at your age). That said, with daily practice, you'll be amazed at what your hands can do in a year or two, and it all comes back to those little millimeter details in precise placement. Not just of your fingers, but your thumb and wrist and knuckles and all the parts of your hand. As you build up strength with daily practice, you'll find your fingers will be able to make some shapes that they couldn't make before. One note on playing the open G chord, if you haven't already figured this out, it's usually best to use your longest finger, the middle finger, for the third fret of the low E string.
Overall, keep practicing, be patient and give it time, and when you start the class, ask your teacher about the areas where you still have trouble. They should be able to easily catch any minor mistakes you're making and also point out ways to optimize your finger positions for your particular hand size and shape.
