I assumed that having rhythm and being able to dance went hand-in-hand. If you can move your body to the rhythm shouldn't you be a good dancer? (assuming no choreography).
Apparently not, but it may also have something to do with me being very uncoordinated in that area. I probably hit my head, or stub my toe multiple times a day. (Which is strange considering my incredible coordination with instruments/tools).
When I was a child, the doctor prescribed dancing school for a gait problem, so I had six years of it when very young and I think I learned to be good with body rhythm for a long time after that, but now I have chronic vertigo issues so mostly being off balance a good deal of the time, I doubt I have that much rhythm now.
I dance like a white-boy, as someone earlier joked similarly. I used to be able to do the robot fairly well, but that just makes me whiter!
But I have an excellent sense of rythem overwise. I walk in rythem, I think in rythems, I am addicted to playing music. I guess my sense of rythem is much more internal. But when I really get into playing guitar, I move my body a lot, but I mostly stomp my feet and swing my arms and body and stuff... but to the beat nonetheless.
