Before there were good ways to record and play back bass sounds, did anybody bother to train their voice to sing low bass? I imagine the uses for the skill would be rather limited before good microphones, recording equipment and widely available hi-fi stereos to play back bass sounds.
I mean, not everyone has to train their voice to sing low notes. If it’s just your natural range, you won’t have much choice but to sing bass.
Anecdotal, but I’ve also had to be called back the one time I was singing in a choir, because I was too loud compared to the rest.
To some degree, I imagine that’s a physics thing, due to having a larger (resonance) body and being able to push more air through the longer vocal cords. But of course, you also simply don’t need to be as present as the melody on top.
