I wouldn't quite say I'm new to singing in general. That would be lying, I suppose... I usually sing to myself a lot, so I'm pretty used to that. The problem just occurs when I try to play the guitar at the same time. My concentration and rhythm just goes right out the window the second I start singing along. I've tried to start simple, using the Rhythm Guitar-part of Patience, which is just a handful of simple Open Chords, but no matter how simple I try to make it, the problem persists, and I have no clue how to get rid of it...
