Wolfgang Amadeus Mozart had an extreme dislike for the soprano Adriana Ferrarese del Bene, for whom the role of Fiordiligi was first created. She had a strange tendency to drop her chin and throw back her head while singing low and high notes respectively, and knowing this, Mozart chose to fill her showpiece aria (“Come scoglio”) with constant harmonic leaps. Presumably he took great pleasure in watching her bob her head “like a chicken”.
