Answer:
If the musical piece belongs to 1914, it represents the Tin Pan Alley.
Explanation:
Tin Pan Alley is the nickname of popular American music from the late nineteenth century to the mid-twentieth century. In the late nineteenth century, musicians usually played the piano in the street and sold their music scores, which were the main source of revenue for publishers and composers. These scores were sold for 30 or 40 cents, and the trade became so popular that some publishers sold their scores to hundreds of thousands of copies.
Some people consider that Tin Pan Alley's music only took off after the Great Depression, when the phonograph and the radio gained popularity. Others consider that the movement manifested itself until the 1950s, until the emergence of rock 'n' roll.
