Acting and Singing by Rebecca McKinley

Singing beautifully is one thing, but being able to portray emotions and a story to an audience is quite another. It doesn't matter whether you are singing in English, French, German, Italian or any other language; if you can't connect to your audience and tell a story, you are missing a major part of your performance. Be sure to thoroughly research the story behind your song and create a subtext, it will add a whole other dimension to your performance.
