Final answer:
Gershwin included meaningless sounds in his compositions to create a specific artistic effect and add a unique element to his music.
Step-by-step explanation:
Gershwin included meaningless sounds in his compositions to create a specific artistic effect and add a unique element to his music. These sounds, often referred to as onomatopoeia, mimic the natural or everyday sounds we hear in our environment.
For example, in Gershwin's famous orchestral composition 'An American in Paris,' he uses car horns, sirens, and other city noises to evoke the bustling energy and chaotic atmosphere of the city.
By incorporating these meaningless sounds, Gershwin aimed to enhance the listener's overall experience and convey specific emotions or storytelling elements in his music.
