So I love to sing. Not that I’m particularly talented, mind you. I just love to do it. For most of my semi-adult life (age 14 on) I’ve considered myself a bass. I’ve got good low range (I bottom out around D2/C2–deep C or “the C below ‘low C'”) and I can push myself to reach E4 (F4 on a really good day–just above middle C (C4)).
And then one day, singing in my car I realizes there aren’t many cool songs for basses. Thus I must improve my upper range and become a baritone or 2nd tenor. Boy, that was fun. So I’ve been experimenting with singing tenor in church choir. Lucky for me, I live in an area where tenors are in plentiful supply (usually good tenors are the hardest to find at church). Thus I have the ability to hear a good tenor in both ear and match where I need to pitch my voice.
Stretching my limits has been very fun. I sang a song over summer that required a G4 (a step and a half above my normal max) that I had to falsetto, but it has been fun to learn to hear the higher range of notes. Bass is easy to pick out because it is the lowest note you hear.
So anyway, I can sing bass better than most, and my tenor is coming along, if a little short on the upper end. Either way I love it.
