I took posted a poll on Facebook, asking "Do you believe that Everyone can sing?" Here are the results:
100% believe that everyone can sing. 75% believe that NOT everyone can sing ON PITCH. And we all agree that not everyone is an artist.
Would you believe me when I tell you that I've found most pitch problems to be caused by improper breathing/support, and that all my clients improve in this area once they start supporting?!!! True!
