Final answer:
In the early 1930s, the music industry was broadly divided by genre and geographical markets, with jazz thriving particularly in urban areas like Harlem and classical music maintaining its audience primarily among the upper class.
Step-by-step explanation:
In the early 1930s, the music industry was not particularly divided between swing and bebop styles or between acoustic and electric instruments. During this time, jazz was expanding its reach and popularity, and the divisions were more along the lines of genre and geographic reach. The vibrant jazz scene had strong roots in African American enclaves like Harlem, and while the burgeoning sounds of swing music were just on the cusp of arising, bebop would not emerge prominently until the 1940s. The advent of electrification was beginning to influence the industry, but the major divide in the music industry during this era was between different genres such as jazz, blues, and classical music, and between the markets they appealed to, often delineated by rural and urban lines. The Jazz Age, also known as the 'Roaring 20s,' is when jazz solidified its place in American culture, with New York establishments like the Cotton Club leading the way in popularizing the genre. At the same time, classical music still held sway among different audiences, primarily the upper class and often supported by aristocracy or the middle class for public concerts. The Great Depression of the 1930s would further influence the music industry, bringing about societal changes that were reflected in the artistic expression of the time, including music. Hence, if a specific split had to be highlighted, it would be between the rural and urban markets, where different musical styles and preferences were rooted.
