Tin Pan Alley

Tin Pan Alley is a genre of popular music that emerged in the United States in the late 19th century. It is characterized by its use of catchy melodies, simple harmonies, and sentimental lyrics. The music was often written for musical theater productions and was popularized by sheet music sales. Many of the most famous American songs of the early 20th century, such as "Over the Rainbow" and "White Christmas," were written in the Tin Pan Alley style.
