Allegro, which concerns a son following in his father's footsteps, represents a "musical experiment" conducted by Rodgers and Hammerstein. Defying "virtually all musical theatre conventions" of the time, its Greek chorus frequently interrupts the narrative, and the show focuses on a larger theme of personal struggle in the face of success. Minimalist in its staging, patterns of light were used to represent both spaces and emotions.
