What is a Bolero and what does Ravel have to do with it?

A bolero is a lively Spanish dance in 3/4 time with a strongly marked rhythm.

The dancers perform intricate steps while keeping time with castanets.

Maurice Ravel published a well-known orchestral version of the dance, Bolero, in 1928.

A bolero is also a short jacket, perhaps first worn during performances of the dance.
