I don't know where my voice belongs, and thats fine by me. At school, I was always made to sing Alto, because I could read music, and we didn't have enough alto's. In folk choir we usually did 3 part harmonies with men and women on each line (so really 6 part harmonies). I usually sang the highest line. When we sang stuff that was written in 4 parts, I used to sing the tenor line, but up an octave.

When I lose my voice, I usually lose my top voice, but also my range gets extended about 3 tones lower at the bottom - notes which I can never normally reach.

And if I am going to perform something in public, I have to raise it about 2 tones from the pitch I practice at, as I can get volume on my high voice, but not my low voice.

And the break between my head voice and my chest voice seems to be different depending on whether I am going up the scale, or down.
