my first time ever in choir was 6th grade. not sure why i joined, but i did. got selected to do a duet with another person, for an event in a large auditorium. was so nervous, i think it made me not want to be involved with choir or music stuff while in school. i never took a music class or sang (in school related stuff) after that.
i like to try and mimic a style, if i can, or at least try and have fun with it. have done throaty metal stuff, a Jimi Hendrix impersonation, maybe an AC/DC-like style, sang in Spanish, and tried and failed at singing in French :D
singing is interesting, much like a guitar, where you can have "effects", it's the same with singing for me, just more challenging. effects would be, clearer, softer, breathy, louder/scream, throaty, nasally, from the belly, more headier, falsetto, closer, further, etc.
unfortunately i had to lower my pitch when i went through puberty, really didn't have control over that :D
