Although audiences seem to love it, many performers question why I like to conduct Leroy Anderson’s holiday piece “Sleigh Ride” so darn quickly. Here’s why: Audiences love it. Well, actually, there’s more to it than that. Usually, when I get to select my own holiday music programs, I often use Sleigh Ride as an encore piece. After all, we all want our audiences to leave a concert full of upbeat energy, wanting more, talking to each other about the wonderful time they just had, and telling others to attend next time. But I’ve also done my research.
