There are times when I move to my thumb to over lap the neck. When I am playing an odd chord or just want to deaden the 6th string. I may lay my thumb along the bottom edge of the neck at times, but most of the time it is just below the center of back of the neck.

I had a few lessons when I was 16 or so. I quit because I thought it was a waste of time. The instructor played well, but he was a lousey teacher.

I will soon be 59 and I recently took 3 lessons and quit again. The instuctor knew his stuff, but moved too fast for this old man to keep up. He looks at his students as if they were all going to be professional guitarists. I don't have the time to dedicate to that. I can play, but I don't know much theory or play at a level that I would say is "Good".

I write lyrics and produce a tune to go along with them. It would take a better musician than I to embellish and make my songs a success. That is why I just sell my songs. I do not have any desire to be a performer.

I guess if it's comfortable, you can hold your guitar anyway you want. I think the way I mentioned is the standard way as far as standard goes!
