Sorry...How to find one. Find out who in the local opera company gives lessons and take them from someone who's a performing professional. Or, at least once was. Make sure you go into it with thick skin because opera people can be intimidating and direct. But, they're usually pretty human under all that pretense and pomp. That was my experience, anyway. She was exacting and relentless and I'll be eternally grateful. Love her madly to this day!
