In 1959, Dr. William Klenz required his undergraduate music history students at Duke University to unlock the secrets of baroque music by studying original texts for what led up to it — social dances of the Renaissance, as taught by dance master Thoinot Arbeau  in his Orchesographie.

Tapping dance sources is now a small but recognized niche (NYT, 9-4-13).

I believe Klenz — who never wore a watch because he didn’t want to be the slave of time, and insisted that all of his students sing “A” upon arising in the morning so that they would be in tune with the world — was an unrecognized genius.
