Paddy brings up an excellent point!!! (as usual) With music your body language is so important! Everything has to be carefully choreographed, instead of scripting you are just using music. It must also reflect you and your personality since it is, in essence, your voice.
That is why you have to find the right music for the right effect-- and why sometimes I get overly excited when I find that "perfect" music, or perfect "illusion". LOL...that is how this whole topic came up yesterday. I was excited because I found that "perfect" piece of music for one of my daughter's illusions. Actually, I didn't find it--- it was given to my daughter to practice with for a different show she will be in soon. While taking a break from practicing she decided to try it with one of her own illusions in her act. It might as well have been written for her!
So with puppy dog eyes and an impish grin smiling at me I wrote the composer and we got the answer back yesterday stating our daughter could use it in her act. Needless to say she was thrilled. The illusion would have never been the same without it.
Find the right music for you----
and you will come alive on stage.
