Damien Chazelle’s Whiplash (2014) tells the story of a driven young jazz drummer and a drill sergeant. O.K. That’s not quite true, but it could be. J.K. Simmons plays Terence Fletcher, a stern, demanding college jazz band director as if he came from Fort Bragg. Fletcher teaches at Schafer College, the fictional best conservatory in the country set somewhere in New York City near Juliard but not quite. The studio jazz band wins competitions. To be on the core team of that band is to be best of the best for college jazz band musicians. Fletcher could be a football coach or drill sergeant, but this movie is a pedagogic drama and set in a college.
