Our hosts finally return to the project they started in Episode 3: answering ten fundamental questions about ballet, and make some serious progress. Lincoln and Elise discuss ballet costumes, sets, steps, style, music, and ballet dancers' hair, and how these things are used to solve design problems within the art. They also discuss the trouble classical art has with convention, a 20th century theory on how pop music differs from classical music, and how hard it is to figure out what Elise looks like.
