Just an aside. I think that most of us sound a lot better to ourselves than we do to others. It is also surprising that some people with mediocre speaking voices, or even somewhat annoying or unpleasant ones, sometimes break into song like angels. Go figure. I like "taking voice lessons" in my head while singing hymns at church, discovering the effects of breathing and how some adjustment in throat muscles can make singing effortless instead of grating. I've been recruited for singing only once, but it was an outdoor event and they needed a bass voice or too, which is roughly where I land. But church choirs and other singing groups recognize my talents, or lack thereof, and I am not bothered with requests to join. There was a guy in boot camp, a kid from New Orleans, who claimed to sing professionally in clubs. He couldn't hold a note nor stay on pitch, nor get on pitch. He always sounded like a drunk in the shower. But he did have confidence, and fortunately, didn't have time in boot camp to sing too much.
