The first musical in history was john kay's The Beggar's Opera, which premiered in London on 1728. It was called "folk opera" at that time, and the songs that were widely circulated at that time were used as the main line of the story. 1750, a traveling troupe first staged a beggar's opera in the northern United States, which was the beginning of Americans' personal experience of musicals. From 65438 to 0866, The Black Devil became the first musical in America. German comedies, "Girls Dancing in Tights", funny songs, costumes of dwarfs and goblins, etc. The strange scene is amazing. Americans' excitement and support for musicals is "like Milan waiting for Puccini's new opera, or Vienna waiting for Brahms' new symphony".
