William Thomas McKinley (December 9, 1938 – February 3, 2015) was an American composer and jazz pianist born in New Kensington, Pennsylvania). He wrote more than 300 musical compositions in what he called a neo-tonal style, of which Margalit Fox writes, for The New York Times, "were known for their lyricism, rhythmic propulsion and accessibility" and adds that his music "could recall not only jazz and blues but also Bach, Debussy, Ravel and Vaughan Williams.". Many of these works have been recorded by such ensembles as the London Symphony Orchestra, the Warsaw Philharmonic Orchestra, the Prague Radio Symphony Orchestra, the Boston Modern Orchestra Project, and the Seattle Symphony.
