Step-by-step explanation:
The popular "hop" of the '20s & '30s that originated in Harlem and is named for an aviator is the Charleston. The dance was influenced by the spirit of the Jazz Age, a time celebrated for its vibrant music and dance culture. Harlem was a central hub during this era, with famous venues such as the Savoy Ballroom and the Apollo Theater. The Charleston became emblematic of the flappers, a group of young women known for challenging social norms and embracing a lifestyle of fashion, music, and uninhibited dance. The dance reflected the high energy and spirited nature of the age, becoming a sensation among young people seeking amusement in dance halls after long workdays. Moreover, jazz music was gaining widespread popularity, with artists like Duke Ellington and Cab Calloway performing in Harlem clubs. It is evident from the broader context of the era that Harlem was the epicenter, both geographically and culturally, of these new forms of entertainment that defined the 1920s.
