I'm finding none. It's the same thing! It's about rhythms and beats and what connects to what. It's the same; the song has to connect to the story to get from this point to that point. So even though there may not be music in the show there is. You have to follow this delicate score. I don't think there's a huge difference. But, I don't have sore muscles! I'm not sore from dancing all day!
