Hi MDEW, the survey is conducted for the research paper that some singers might find helpful. So, in a way, it's a global contribution. I don't agree, not always, in my research, I will try to validate all the answers considering academic resources and previous studies. My survey is not about theatre type performance; it is not about actors; it is about the persona that we adopt; the persona that acts as an extension of our true self. I agree about the dancing part; it does require the particular degree of concentration that we all can achieve by practising regularly. However, here's the thing, what's the point of singing (telling the story) if you don't wish to share and instead chose to ignore the audience. Automatically, the performance without an audience or the consideration of audience in not a performance anymore.
