Are you LISTENING to yourself when you sing?  If so, then STOP! "Wait. What"? Yes. It's true! You can't LISTEN to yourself and sing well at the same time.  This doesn't mean to sing off-key or to throw pitch and musicality out the window.  It means that listening to ourselves puts us in a physical and mental state that isn't conducive to our best singing. Physically, the body and breath lock up when we listen really hard for things. Mentally, we get into a judgmental, critical, and analytical mindset when we listen really hard to ourselves. Singers who listen too hard to themselves often sound contrived, planned, and stiff as well. Instead of listening, try TRUSTING your ears. Trust your body, breath, and resonance too. Your audience will do the listening! You can do the Trusting!
