I should have probably put the word really in bold italics.
When it comes to how we really come off to an audience both visually and vocally, there can can be a wide gap between our perception as performers and the perception of the audience.
This is of course important in performance, but equally as important in auditions, when how you sell your piece or pieces can play a big part in determining whether or not you are hired!
So....and I have said this before, use every means at your disposal to make sure you are putting across what you want to put across.....
Colleagues, teachers, coaches, mirror, video recordings - all are good ways to find out if that is happening!
