Is it a bad thing, if constantly look at the frets while playing? Some times I find by self curved over a body of the guitar so much, that my neck starts to hurt.
Seems, that some experienced players do not look at frets at all, while others do. Here is a great musician, for example, that looks at frets so close that it just doesn't look right http://www.youtube.com/watch?v=ShY50pxA_W4 :)
Should I get rid of this habit and try playing "blind", not looking at the frets? Will it give me some advantages?
