My daughter and I attended a tap performance this afternoon. We just watched the first half, when the professional dancers performed. We didn't stay for the tip-top tap-school performances.
The pros were all excellent. But... I wish they had danced to music more often. There was a perfectly good jazz trio on stage, ready to play any standard on request. But contemporary tap dancers seem to be in love with just dancing to their own percussion.
I don't mind this in the middle of a performance, where they dance for a while on their own, then the music starts up again. That has the effect of a drum solo, and I like it fine.
Tap without music is amazingly athletic
But strays from the aesthetic.
