Hey Bob, Welcome to the chordie forum! I see you've posted in the section assigned about Jamplay. If
interested in learning online I will say that jamplay is a very good sight as I also am a member.
They give great lessons on all types of playing including how to read tab however not a free site but
you can check it out for free. If not interested try posting your question in the music theory part
because there are alot of people that use tab and can give great explanations. I use tab rarely.....
sorry-but maybe the free site: justinguitar.com might help, Mike
