did the bigger, more highly arranged bands. The 1939 recording of "Body and Soul" by Coleman Hawkins with a small band featured an extended saxophone solo with minimal reference to the theme that was unique in recorded jazz, and which would become characteristic of bebop. That solo showed a sophisticated harmonic exploration of the composition, with implied passing chords. Hawkins would eventually go on to lead the first formal recording of the bebop style in early 1944. Going beyond swing in New York As the 1930s turned to the 1940s, Parker went to New York as a featured player in the Jay McShann Orchestra. In New York he found other musicians who were exploring the harmonic and melodic limits of their music, including Dizzy Gillespie, a Roy Eldridge-influenced trumpet player who, like Parker, was exploring ideas based on upper chord intervals, beyond the seventh chords that had traditionally defined jazz harmony. While Gillespie was with Cab Calloway, he practiced with bassist Milt Hinton and developed some of the key harmonic and chordal innovations that would be the cornerstones of the new music; Parker did the same with bassist Gene Ramey while with McShann's group. Guitarist Charlie Christian, who had arrived in New York in 1939 was, like Parker, an innovator extending a southwestern style. Christian's major influence was in the realm of rhythmic phrasing. Christian commonly emphasized weak beats and off beats and often ended his phrases on the second half of the fourth beat. Christian experimented with asymmetrical phrasing, which was to become a core element of the new bop style. Bud Powell was pushing forward with a rhythmically streamlined, harmonically sophisticated, virtuosic piano style and Thelonious Monk was adapting the new harmonic ideas to his style that was rooted in Harlem stride piano playing. Drummers such as Kenny Clarke and Max Roach were extending the path set by Jo Jones, adding the ride cymbal to the high hat cymbal as a primary timekeeper and reserving the bass drum for accents. Bass drum accents were colloquially termed "bombs", which referenced events in the world outside of New York as the new music was being developed. The new style of drumming supported and responded to soloists with accents and fills, almost like a shifting call and response. This change increased the importance of the string bass. Now, the bass not only maintained the music's harmonic foundation, but also became responsible
