Swingmatism is a jazz standard, composed by William Scott, and featuring Charlie Parker.[1] It was originally recorded on April 30 1941 with Gus Johnson, though the best known version dates to 1942. According to author Dave Oliphant it "illustrates how, with a good 'swing' rhythm section, one can play bebop and still have it fit."[2] The tune, composed in F Minor,[3] is noted for its "sixteen-bar sections in the minor and modulation to the parallel major, through the use of a diminished chord".[1]
