This is the first time that this has happened to me. I was singing my 5-a-day just as the Doctor prescribed (my teacher told me to sing 5 high B-flats every day until my next lesson) and I *literally* had to sit down after every single one until my head stopped pounding.
Is this what you high-voiced people go through every day? How miserable!! It happened on A's as well, but it wasn't the same kind of awful throbbing. No wonder why I've always instinctively avoided these notes. self-protection.
I literally make a little hatch mark in my calendar for every high Bb so that I can honestly say that I've sung five that day. I almost couldn't get up off the bench for number 5 today, but you know how the 5th one is the cross-hatch and finishes the group. I like to finish things.
I am also starting to love some of the lyric arias I sing. I think I might like to try this out, singing the heroines instead of the mothers (or pirates)....
My husband and I are both opera singers, and in the fall we moved from NYC to Michigan, where he is now a professor of voice and opera at Oakland University. In January we bought our first house-- an 1895 Victorian, and we're expecting our first child (a boy) in April.
