When you overblow a note, it produces the corresponding note for that fingering in the next register. So if you play clarion G, for example, and then "overblow", you will hear altissimo E, while still holding the clarion G fingering. I'm not sure what exactly I do for the note to overblow, but it may be a subtle change in embouchure, or the shape within my mouth. I just know that the sound suddenly "jumps" to the next register.
The surprise for me is that the altissimo notes E and F seem to be relatively free-blowing - certainly much more then I had thought. When I keep that feel and play the correct altissimo fingering, the notes speak easily.
Perhaps some one else will have a more technical understanding and explanation!
