now, having nearly completely my first semester as a voice major at nazareth college, my voice teacher has me warming up to F6's!! AAAHHHH!!!! she has deemed me a lyric mezzo. sometimes i'm glad, sometimes i'm very very sad. i will always and forever sing alto in choir because i can and do sing those D3s.
and its healthy to extend your range higher and lower. i'm proud of my 3+ octave range :D
what about you? what is your official classification?
