The most important jazz musicians are the ones who are successful in creating their own original world of music with its own rules, logic, and surprises. Thelonious Monk, who was criticized by observers who failed to listen to his music on its own terms, suffered through a decade of neglect before he was suddenly acclaimed as a genius; his music had not changed one bit in the interim. In fact, one of the more remarkable aspects of Monk's music was that it was fully formed by 1947 and he saw no need to alter his playing or compositional style in the slightest during the next 25 years.
