LAST EDITED ON 04-15-12 AT 10:46 AM (EST)This subject has always confused me. And this doesn't help.
"Taking a portion of an existing musical work, and putting it in a show, video, or another musical work. Not to be confused with interpolation, which is replaying the said portion. "
Taking a work and putting it in a show isn't "Replaying"?
And I had not heard of musical "interpolation", that's always been a handy mathematical tool to me.
Then, of course, there's the musical "trope", which is somehow different from other musical insertions and other tropes.
Oh well.
