Cartoon Trivia ANSWERS with Leo & Peri [UPDATE]

Léonin (b. 1150?) was the first known composer; Pérotin (b. 1200?) was the second known composer.

Having known so much, we present Classicalite's Cartoon Trivia with Leo & Peri.

Leo: "Peri, I have just finished reading a treatise--about our own music, no less! It was written by a guy named Professor F. Ludwig. Honestly, it was kinda boring. And he kept using this word I'd never heard of: isorhythm. In fact, he claims we both used isorhythms all the time. What is an isorhythm, Peri?"

Peri: "My dear Leo, I'm sorry to hear you found Friedrich Ludwig's work on isorhythms so, umm, uninspiring. They're really quite exciting--especially when applied to our motets! Put simply, an isorhythm is a fixed set of pitches played with a repeating rhythmic pattern. The rhythm pattern is called the talea; the pitch set is the color. And I might remind you that it's not just us old fogeys that have utilized isorhythms."

Do you know the answer, Classicalites? If so, let us know in the comments. As always, we'll post the right response soon.
