Foolstroupe said: I had to just make it work by 'thinking the notes'

This may be what I was trying to explain when I posted a message above, about shaping the notes before they hit the instrument.

Consider the Alpenhorn, which is many feet long long and rests on the ground in front of the player's feet. Obviously any changes in the pitch have to come from the player's mouth, throat or lungs, because there is absolutely nothing to touch.

Hold on a minute, and I'll post a link.
