Good jazz is when the leader jumps on the piano, waves his arms, and yells. Fine jazz is when a tenorman lifts his foot in the air. Great jazz is when he heaves a piercing note for 32 bars and collapses on his hands and knees. A pure genius of jazz is manifested when he and the rest of the orchestra runaround the room while the rhythm section grimaces and dances around their instruments. — Charles Mingus
