The most important thing to trust, though, is ourselves. Our bodies are amazing! Our ability to hear tones and recreate them with our bodies is amazing! Singing is amazing! But if we don’t trust that our bodies can do it, we cannot achieve good singing.
In order to really sing well, we have to give up our fears that we will sound less than perfect and trust our bodies. We have to accept that ugly sounds are part of the beauty of singing and that making a mistake is not bad and nothing that we need to apologize for. We need to trust that those ugly sounds that make us uncomfortable and those mistakes that we hate making will lead us to our goal of consistently beautiful singing.
