Black belt caterpillar wrestler: yes.

The "Vocal Range Information" above gives too small ranges, even for amateur singers performing choral music. See more accurate information on Wikipedia etc. Also note that "range" is not the whole truth about a voice and its training; it's the quality of each register that matters. If your Bb2 can fill an opera house with steady and modulatable sound, you're a rare bird, whereas mine can easily fill my shower room when I have a cold. However, to sing bass opera roles such as Ochs von Lerchenau, you must have an F3 as well. That takes years to decades of intensive professional training.

If you compose for other singers (as I sometimes do), either consult them regularly or keep to the middle of the road.
