It's been rehashed ad nauseam, so I'm not here to argue the whole close fingers v. far fingers thing. All I'm gonna say about it is I'm in the Kalmen Opperman camp, by way of his influence on my teachers...the less motion and distance, the better...YMMV.
Possibly even more important is to look at the hand position. It shouldn't be moving around to facilitate the register key, throat tones, trill keys, etc... Similar to good palm key technique on saxophone (though that's a little more forgiving, and you can get away with more motion than on clarinet).
And Gordon, I'm not trying to get into arguments with you cause it's futile (since we both clearly have the opposite opinions) but I am always amused by your analogies using things that are semi-related to playing instruments. I don't understand your clapping analogy...it's unnecessary to use more distance/force to get some "snap" in your pads...this neither makes notes come out faster or sound better. Elaborate? (this is not a challenge, I'm in fact curious about your POV).
