I sing soprano with the Chicago Chorale, an all-volunteer choral organization with an audition requirement. To sing with the Chorale you need to be able to sing two arias, one in German, sight read, generally be able to produce a reasonably accurate pitch and attractive tone quality and generally be a nice person. It's selective but not so selective that the director only takes professionally trained singers. When I auditioned, at 36, I hadn't sung since undergrad. I didn't own a piano. I found my aria books in the bottom of a box. I practiced, on short notice, for three days. It was a rough audition. But, one way or another, they let me sing! My natural tone quality is high, thin and whistly. That technique works, in a choir, but it's a fast track to throat pain and nodes. I was struggling with the range and couldn't produce the volume I wanted to hear so I asked my section who they would recommend for voice lessons. On day one Thomas transformed my whistle into something Puccini would have, okay let's be honest, Puccini would've been irritated but it was a heck of a lot closer to what Puccini would've been looking for than the whistle ever was. I learned how to adjust my breathing and vocal anatomy to produce a full tone at a much louder dynamic while maintaining an attractive tone quality. After that, the hoarseness and pain in my throat with which I ended every rehearsal went away. Thomas is seriously a miracle worker. If you're doubting, just try it. Take it from me. You'll hear the difference within the first hour.
