Comments about ‘Was jazz shaped by dancing?’

A connection between Jazz music and dance is hardly news to anyone with a knowledge of Jazz. It is why the music was considered so dangerous to the Puritan American tastes. Its based on African polyrhythms via European instruments.

Apparently you didn't read the article. It's not a newfound connection between jazz and dance - it's that instead of jazz influencing dance, which you so intelligently stated, is well known, but rather dance possibly influenced jazz - a relative unknown to this point. Armstrong altered his style and structure to match dance steps and movement, the reverse of the usual - which is a dancer timing their movement and steps to the beat and swing of the music.
