When we bought the DVD set I watched Jurassic Bark once and swore never again. No show has ever reduced me to a blubbering mess that quickly (although the opening scene of Pixar's 'UP' is a pretty close second.)

In fact, a small, brown unloved mongrel who looked just like Seymour owes his life to my family seeing that episode.

Tracking the baton movement could be fairly difficult though. Even squeezing out a beat while concentrating on singing might be more difficult than it appears. I mean, just following the conductor rather than the musicians around you can be a challenge even for experienced musicians. I've done a fair bit of conducting, and I know how hard it can be to get a band to realise you actually want them to go a bit faster! Getting someone to do that and communicate it in two dimensions in real time while actually singing properly... that would be a special singer indeed!

Actually, that could be a rather interesting exercise. Getting members of the choir to track the conductor's movement on someone else's hand (who then have to concentrate on the hand signals rather than what other people are singing) could be a good way to reinforce the importance of paying attention to the dude/dudette with the stick!

I've been sitting at my desk for the last couple of minutes studying my own conducting style. I've always tried to maintain a very clear beat (a lot of my conducting over the years has involved beginner bands, so communicating where the beat is is far more important than it might be in more professional outfits.)

Anyway, I've noticed that my style is very three dimensional. My upbeat, for example, starts near my sternum, goes out from my body and follows a roughly circular path back to near my forehead. The other beats seem to do similar things. Now that I'm looking at it, that back-and-forward axis is quite pronounced, and may explain why my tuba players (who sit on my immediate right) never complain that they can't read my conducting.

Which goes to your original point---depending on the conductor, a side mounted camera might actually work, so long as it can still read two directions.

The problem I have now is that I'm going to be very, VERY conscious of my style come Thursday night!

The reason (I'm spitballing here) that I think the beat come at the point of highest acceleration is that that is the point when the conductor applies the most force to his or her arm. It's been years since I studied physics (or physiology) but I imagine that would be very close to the point of highest acceleration.

All that said, I've had conductors that seem to anticipate their own beat. For them, the beat actually comes just after they hit the bottom. In fact, it probably come at the moment of highest acceleration of the little 'bounce' that follows the beat (which is probably the curve upwards you mention).

You're certainly right about the other cues. They're probably not so important though, so long as the song goes more or less as it does in rehearsal. A blind person will have some idea of what is about to happen (although I'll grant that it's not ideal.) Guessing the exact moment when the first note is meant to be sung to within a very small fraction of a second isn't something I'd enjoy.
