Recently I was talking to a magician who wanted to use music in a close up set. Lots of magicians have done this. It’s usually done in more formal close up or really a small parlor show and not in a roving magic context. For me one of the early example of this was Jean Pierre Vallarino on the World’s Greatest Magic in the 1990’s.
More recently this has gained popularity with Shin Lim’s performances on America’s Got Talent. One thing about Shin’s performance is that it’s really not a “Close Up” act, it’s a parlor act and I think a lot of magicians don’t realize that because it feels more intimate on TV. I’m not saying it can’t be done close up, but it’s bigger than most close up.
Back to using music in close up. One of the great things about close up is that you can quickly and easily connect with people, and with music you are staring out with a wall. It’s a “I’m the performer, you are the audience” scenario. There’s nothing wrong with that, but it does make it harder to connect.
Personally I prefer a “we’re in this together” vibe to my show. That is easier to accomplish by talking with people. However, that’s just me, and if we all did everything the same way, the world would be boring.
