Step-by-step explanation:
Carnegie Hall is mostly used for musical performances, specifically catering to the tastes of the urban elites who preferred sophisticated and cultured entertainment. It was founded in 1891 by Andrew Carnegie as a center for classical music in New York and continues to serve as an iconic venue for a wide array of performances, including symphonies, chamber music, and solo recitals. Unlike amusement parks and baseball games which drew the working class, Carnegie Hall underscored the knowledge of art and culture among the upper class, who valued refined pastimes and social gatherings with peers.
