Aaron Copland's Scherzo Humoristique," written in 1920, is indeed musically humorous as it depicts the skittering rodent and sinister feline in a demanding, but very enjoyable etude setting, using complex 1/16 note patterns, glissando, grace notes, chromatic scale work, and a generous use of the entire keyboard. There are sudden shifts in tempo and dynamics, and the performer tells a definite story, albeit without narration. Large hand reaches, sometimes 9ths, are required on some of the full block chords.
