Question:

Is there a way i can sound better when i sing cause, i have an audition coming up and need to sound better.?

someone told me to do breath exercises and they help sing longer but not sound better, i don't sound horrible when i sing but sound as if i'm straining and i am and my throat hurts after word. Is there anyone that can help sound better and not strain my voice or hurt my throat trying to do it...
