metronome

This video on walter Lantz at around 3:15 had a quick glimpse of a 2D guy using a metronome. He sets it and then used his fingers as if they were legs, step step step step hop step step in time to the metronome, then changed the speed and tried again. Makes sense, you can set the metronome to 8's or 4's or 16's or whatever, and then you are visualizing to a beat, the mirror image of animating to one.
