I read but don't post much. If I see a topic that moves me enough or somewhere where I can offer help or insight, I'll chime in. I see I'm going to have to be on my toes around you though...LOL!

I'll add a quick comment to your last reply.

Music is melody and harmony set to a rhythm and arranged in time. A song would contain these same elements plus a lyric. A copyright on a song or musical composition will only cover the musical elements such as the melody, harmony, lyric, rhythm and arrangement. Tone, frequency, pitch and timbre aren't purely musical elements. They enhance music but are more related to the physics of sound. Even a copyright on a sound recording would disregard the engineering aspects of it and focus on the musical aspects.

peace...
