oi. If the legal-types are right, then this goes both ways. After all, if a copyright violation occurs when just a few chords are exhibited in a lesson in the same order and time sequence as a copyright song, can't an argument be made for prior art in every short sequence (or long sequence) of chords in the same sequence and relative time duration, busting a standing copyright?
If this is the case, a lot of popular music is coming down. Vide: http://www.youtube.com/watch?v=JdxkVQy7QLM (be patient, wait for the end.) ray To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
