I took a ballet class in college to improve my football. Years later, I returned to dance. This book is about how one dance comes together, from choreography to opening night. I went to performances at Alvin Ailey and Mark Morris, and a modern dance class at Berkeley. Watching the dancers in that class — stretching, sweating, drinking water, practicing each move until they got it right — gave me a big appreciation for all the athleticism and work that goes into creating a dance.
