Dance music is different

I learned something important recently: Dance music is its own species. Music that is intended for dancing goes by too slowly if you're sitting in one place and concentrating; music that is intended to be listened to carefully flies by too quickly when you're dancing. Which means that if you're a composer, and you're writing dance music while sitting still, you have to adjust your sense of time.

Do different times make different people?

I've been scanning negatives from the early 1970s, when I was in college. Some of them are of people who were involved in the then-new computer chess world. Makes me wonder: How would my life have been different if computers were everywhere when I was in college, rather than being expensive, specialized devices that could fill a house?
