OK, I've been accused of singing offkey. Sounded fine to me, at the time. Then I learned to hear that it was off, now I can sing on key, say musicians. I haven't got a clue what a key really is... but I think it's why I can't sing along with half of what I used to. Tell me, those of you who know more - now, when singing along, if I want to stay with the artist, I have to start either too low for the low notes or too high for the high notes. It was easier when I sang what I wanted and everybody else cringed. Is that because my ear and voice know what key I'm supposed to be in? What can I do to expand my range, if that's the problem with singing on key? Also, am I allowed to change octaves in the middle to keep with the artist, or do people who can sing hate that? So what IS a key, anyway, and why is being able to sing on one such a curse for me, who really only likes to sing along? Aargh!
