I am new to the internet and have been trying to find some particular tunes. In the process, I'm coming across these terms that I don't understand. Is there a place on the internet I can go (must be!) where I can get real BASIC instruction on these different formats? I'm not sure what they mean and now I'm finding that they can be converted one to another. What I'm interested in is seeing the sheet music. Am I the only one with this question? If this is an inappropriate thread, I apologize. Rosebrook
