Henderson has been described as «one of the great chord change players of jazz history», and this aspect of his playing, that had its roots in bebop and Sonny Rollins’ approach to improvisation, is very apparent in the repertoire of songs he chose to play that night, each piece with interesting chord changes beginning with Thelonious Monk’s Ask Me Now. Although Henderson’s style grew out of Rollins’ sense of phrasing, rhythmically Henderson was a lot looser and built on Rollins’s style to create his own approach to improvisation.
