I had wondered who was receiving replies too, but, this is a thank you
intended for you. I received the whistle pattern and have attempted to master
it. If I fail, I'll ask my daughter, a music major at McGill, and maybe she
can explain to me how a simple whistle works!!! Your illustration is
outstanding, with all the necessary details, I'm sure, but I'm still trying
to get a decent sound! I shall persevere. Thanks again.
