Thanks, Vixen.

One of the reasons I'm getting a headache now is because for many years, any time I have played music with people who were using "modern" instruments, they have consistantly told me that my recorders were playing flat, regardless of how warmed up they were. I have been blowing as hard as I was taught to do when I took lessons at the Washington DC capter of the American Recorder Society back in (I think) 1972. They were very careful to stress the importance of not overblowing, and they also showed us how much is enough and how much is too much.
