Tin Pan Alley

From Wikipedia:

Tin Pan Alley was the collection of New York City music publishers and songwriters who dominated the popular music of the United States in the late 19th century and early 20th century. The name originally referred to a specific place: West 28th Street between Fifth and Sixth Avenues in the Flower District^[2] of Manhattan; a plaque (see below) on the sidewalk on 28th Street between Broadway and Sixth commemorates it.^[3][4][5][6] In 2019 the New York City Landmarks Preservation Commission took up the question of preserving five buildings on the north side of the street as a Tin Pan Alley Historic District.^[7]

The start of Tin Pan Alley is usually dated to about 1885, when a number of music publishers set up shop in the same district of Manhattan. The end of Tin Pan Alley is less clear cut. Some date it to the start of the Great Depression in the 1930s when the phonograph, radio, and motion pictures supplanted sheet music as the driving force of American popular music, while others consider Tin Pan Alley to have continued into the 1950s when earlier styles of music were upstaged by the rise of rock & roll, which was centered on the Brill Building.
