Trivia question .... when I was a kid, I remember watching something on TV where a gymnast didn't have her floor music at the event. A pianist watched the gymnast during her routine and was able to like play some random music to match her moves. I'm pretty sure I'm not imagining this, but I was a kid so I could be.

I can remember the coach, gymnast, pianist sort of huddle together quickly describing her routine, and the pianist just watched her and played this random music that went along with her movements. I even remember at the end the gymnast did a little wrist flick. This had to be the 70s as I'd have no memory of anything earlier.

Does that sound vaguely familiar to anyone?
