The Philosophy of Jazz
Jazz is the most flexible art form ever because it believes in the good taste of individuals. It believes in our ability to make reasonable choices. It takes a chance on our decision-making skills instead of legislating our freedom away with written restrictions and restrictive hierarchies. In jazz, the size of your heart and your ability to play determine your position in the band. The philosophy of jazz is rooted in the elevation and enrichment of people, plain ol’ folks.
— Wynton Marsalis, 2008
