when more complicated parts, runs or riffs happen, I generally do NOT look at my fretting hand because I have found that, once I know the part, if I look at my hands, I am more likely to clam than if I just play the part and not look. I don't really understand this, but I know it to be true for me.
I do look to orient my fretting hand, and make sure my fingers are where I think they are, but I generally do not watch my left hand. Your ear will also tell you if your in the right place too (as long as you can hear the mix well).
I don't worry about it too much anyway![]()
Some of the sheet music I play through is pretty complicated and there's no way I can play some of it without looking somewhat. Especially past the 12th fret. It's not stuff that I memorize either usually so I don't know the music at all. New stuff almost daily. Sight reading for me is like reading a book, I do it on the fly and don't memorize parts. I'm pretty picky about it also and try to be as perfect as I can be. Rock songs and stuff with the band I play repeatedly, and memorize and get to know is different for me.
Then everyone is at a different level, you might be a lot better than I !! Rock or jazz on !
