Sunday, Jan. 28, 2001 Charlie Parker, 1949. b. Aug. 29, 1920, Kansas City, Kan., U.S. d. March 12, 1955, New York, N.Y. byname of CHARLES CHRISTOPHER PARKER, JR., also called BIRD, OR YARDBIRD American alto saxophonist, composer, and bandleader who is considered by many to have been the greatest improviser in jazz history and the father of the modern jazz style known as bebop. His first recordings with trumpeter Dizzy Gillespie during the mid-1940s set the pace for the jazz of the next two decades. (See Gillespie and Parker, "Hot House." and Charlie Parker, "Parker's Mood.") Parker's style began with the advanced swing-era approaches of Buster Smith and Lester Young, heard by him during the 1930s in Kansas City, Mo. In 1939 Parker moved to New York City, playing at Monroe's Uptown House on 52nd Street. After playing in the Earl Hines and Billy Eckstine bands with Dizzy Gillespie, Parker and Gillespie left to front their own quintet in 1945. The Dial and Savoy recordings of the late 1940s contain the definitive examples of Parker's playing, including such tunes as "Now's the Time," "Billie's Bounce," and "KoKo." Parker absorbed a wide range of musical influences, including Afro-American folk forms as well as 20th-century concert music. His favourite musical phrases became the vocabulary of, and eventually provided the melodic clichés for, modern jazz improvisers. More than 20 years after his death, new recordings of such tunes of his as "Confirmation," "Donna Lee," "Scrapple from the Apple," and "Ornithology" were still being made. His music became the subject of scholarly treatises and was taught within the college jazz curriculum. Most influential innovators who followed him had at least some of their roots in his style; saxophonists Sonny Rollins, John Coltrane, and Ornette Coleman all showed some Parker influence in their earliest recordings. Parker made common the use of quick tempos and the practice of adding and implying extra chords within existing chord progressions. His phrasings employed unique hesitations and abrupt endings.
