Dumb question--does ABC notation work in languages other than English? Does the Italian (etc) language use its own alphabet to notate music? I would assume so, and if so, then a person must need to understand the English alphabet in order to understand ABC notation. Only a small problem, right? Hmmmmmmmm. Requires some thought.

I don't know either of these, but it could come up again, with tunes I do know.
