Pain In Shoulder

It seems like no matter how i sit with the guitar, it eventually starts to hurt in my shoulder, in the muscle that's on the outside of the arm. If you know what I mean.

I concentrate a lot about relaxing that arm, but it doesn't seem to help. Is the problem my position, or am I just weak in the muscle?

Picking Hand Technique

Hi!

I've been playing guitar for a few years now, about 12-13.
But I've just recently discovered that there might be something wrong with my right hand (pick) technique.
I've been trying forever to build up speed in my picking hand, but still can't pick any fast.

What I do when I pick, is that I pick with my underarm and not my wrist, as I think it should be.
My arm often cramp up, but I didn't realize what it was until just recently.

Is there any good exercises to get rid of my bad picking technique, and pick correctly?

Backing Tracks In Seperate A Window

Hi!

I noticed a new thing here; when I click backing track it shows where the video is.
I actually don't like this because now i have to manually open a new window for it.
I liked the old thing where i could press "Backing tracks" and a little window would pop up, and then I could press to view the tab, that way I could easily manage the backing tracks as I read the tab.

I also noticed a bug when I pressed backing tracks, the video didn't stop.

Except that, great work! And I'm so glad I joined!
