This post is almost identical to my last one. I changed a few words to show how the skill of listening can be applied to your own singing voice.
Your mind is designed to keep you safely where you are. Pay attention to your thoughts as you are singing. Instead of being purely open to the sounds coming from you, you are likely to be deciding whether or not you approve of them. Or automatically trying to understand them in the context of what you already know and are familiar with.
These automatic mental habits will water down the information available or cause you to reject it completely. You may stay safe but you'll be stuck in your current level of technique. After all, maybe the new sounds aren't like anything you've ever produced before.
The next time you are singing, see if you can suspend your thoughts and hear the sound as JUST a sound. You don't have to like it or dislike it or do anything at all with it at this point. Just LISTEN. You will not only increase your chance of learning something new, you will also give yourself the gift of freedom to explore. And that's a step toward your brilliance.
Try this first at your next voice lesson. See if your technique doesn't improve as if by magic! Advanced level: listen in this open way during your next performance.
