Helen,

That is beautiful! It clearly shows how one can have animation with sound. I
strongly recommend your notebook for anyone wanting to learn the technique.
(The link is below.)

I also received a very nicely done notebook from Rob Rudd illustrating
another animation with sound. It is a Jacob's Ladder, an electrical
demostration device that has a rising electrical spark between two slightly
diverging wires. The animation shows the spark with quasirandom static. I
hope he will also make his notebook available.

The Mathematica Help does clearly say that sound primitives can be included
in Graphics and Graphics3D objects. When this is done the Sound plot is
eliminated to be replaced by the specified graphic. I completely missed this
feature.

Well, you *can* do that.

For an extremely silly example that I threw together during final exam
week one semester (I was procrastinating on the grading), see
