Many popular tunes work with chord sequences that are so generic and nondescript that it would be ridiculous to claim a copyright on them. For example, something such as C Am7 Dm7 G7 C Am7 Dm7 G7 Em7 A7 Dm7 G7 C Am7 Dm7 G7 is fair game by any account. On the other hand, there are *also* songs where the harmonic structure forms a significant part of the composer's artistic expression. For example, one might probably get into trouble for mass-distributing the chords for _The Shadow Of Your Smile_ without permission. Somewhere in between those two examples there is a line, with a wide and fuzzy grey area around it. For the purpose of providing examples, it would be prudent to stick to very generic changes, and music that has passed into the public domain. -- Henning Makholm "What the hedgehog sang is not evidence."
