Scott believed in composing and playing by ear. He composed not on paper but "on his band"—by humming phrases to his sidemen or by demonstrating riffs and rhythms on the keyboard and instructing players to interpret his cues. It was all done by ear with no written scores, a process known as head arrangements). Scott, who was also a savvy sound engineer, recorded the band's rehearsals on discs and used the recordings as references to develop his compositions. He reworked, re-sequenced, and deleted passages, and added themes from other discs to construct finished works. During the developmental process, he let his players improvise, but once complete, he regarded a piece as relatively fixed and permitted little further improvisation. Scott controlled the band's repertoire and style, but he rarely took piano solos, preferring to direct the band from the keyboard and leave solos and leads to his sidemen. He also had a penchant for adapting classical motifs in his compositions.
