Last night I attended an incandescent performance by Yo Yo Ma and the Silk Road Ensemble. In the middle of a particularly flamboyant piece of tabla virtuosity, I found myself thinking about the similarities between musical rhythms and game timing. Even the most complex polyrhythms are really just the same thing as a fixed timestep game loop that doesn't match the monitor refresh rate, while many 19th century romantic compositions can be explained as the result of setting Game.IsFixedTimeStep = false.
It made sense to me at the time, anyway :-)
