Yep - though apologies for mentioning it that way, as it must have sounded a bit like I was preening my feathers :-s. I was a professional singer for about a decade, though I never earned more than half my living that way. The last three or so years of it I was a fulltime freelancer, copyediting and proofreading to pay the bills singing everywhere I could didn't cover. As for what I sang: anything anyone would hire me to sing :-). Mostly classical, for a value thereof that ranged from Medieval to twentieth century, and mostly choral/ensemble, which I loved. There is nothing in this world like being one of a small, true-voiced, spot-on choir making actual, honest-to-God, effortless-seeming, bone-deep music. ...okay, so: although I've gotten past a lot of my grief at no longer being a singer, some days I still miss it like oxygen.

Anyway. As a pro, I sang whatever I could get someone to hire me to sing. English choral music, weddings and funerals, American tunes from the Colonial period, plainsong, vocal jazz; tenor, boy soprano, the mezzo I really was. I enjoyed it - I've always been a journeyman performer at heart, rather than the soloist specialist type - but it alchemized singing for me in some odd ways. Avocation to profession: not a bump-free road.
