Thanks for all the posts, cards and letters about my 11th/12th position post. Now I can return, armed with 25 emails, and tell my friends that I was right and they were wrong. Here's what I learned--
I can tell them that when I have a C harp and am playing in F: - -I am playing in the 12th position
But it is harp-chic to say: - -I am playing in the 1st flat position (in the circle of fourths)
And that when I am playing the C harp in the key of G: - -I am playing in the 11th flat position.
If I don't have this right, I am sure you will correct me.
