Dancing for Dolphins

Before we can offer them a performance, we need to introduce dolphins to the concept of an Amphitheater. Certain difficulties need to be overcome, such as the tendency for water to flow downhill and flood the stage (carrying the dolphin audience with it, unpleasantly).

Nevertheless, there is a known solution, the "fish ladder". An appropriately designed ladder could easily allow dolphins to jump from the lowest level (sea level) to successively higher water-tanks that curve halfway around the stage. And of course any dolphins in such a tank could poke their heads out of the water and look down toward the stage. It could be noted that simply because they typically won't stick their heads out very far, adjacent tank-levels don't need to differ a lot in height, making it even easier for them to shift between levels.

While it is known that dolphins primarily use sonar to see stuff, their eyesight is still pretty good. They should see people on the stage well enough. The overall motions of dancers in particular are something that this audience could certainly see well enough to appreciate.

I can't say whether or not dolphins would like human music. Dancers more-or-less need it to help the timings of their motions. Anyway, synchronized motions of groups of dancers, various acrobatic maneuvers, and pirouettes are certainly things that should be able to rivet the attention of dolphins (for all predators, the eyes are attracted to motion, heh!).

If they enjoy the performance, then we can expect them to return, with friends. Then all we have to do is figure out how to charge them admission!
