Final answer:
A satirical cartoon might depict Berlioz with exaggeratedly large orchestras or a comical amount of instruments, mocking his known use of large ensembles for orchestration.
Step-by-step explanation:
A satirical cartoon mocking Berlioz's excessive instrumentation might picture him with overwhelming arrays of musical instruments or absurdly large orchestras, perhaps even caricatures of Berlioz himself wielding numerous batons or being buried under heaps of sheet music. Hector Berlioz was known for his grandiose and innovative orchestration, often requiring large ensembles with an array of instruments not typically used together, and such cartoons might exaggerate these aspects for comedic effect. It's important to recognize that satire uses humor, exaggeration, and ridicule to criticize or mock, in this case, the composer's penchant for large-scale musical forces.
