Sorry I missed chat...been busy listening to myself sing in various keys of flat. I don't know what's going on with me...I've never been known to sing flat before. I would blame the recorder, but then I would be projecting the problem onto a machine that in and of itself is designed to force me to hear exactly what it has recorded. I will say, though, that there are times that I don't sound like I'm even singing the song I started out singing, and I KNOW I'm better than that, so...who knows. All I can do is concentrate more on being on pitch and practice, practice, practice.
