Music industry
Early history: Printed music in Europe

Music publishing using machine-printed sheet music developed during the Renaissance music era in the mid-15th century. The development of music publication followed the evolution of printing technologies that were first developed for printing regular books. After the mid-15th century, mechanical techniques for printing sheet music were first developed. The earliest example, a set of liturgical chants, dates from about 1465, shortly after the Gutenberg Bible was printed. Prior to this time, music had to be copied out by hand. To copy music notation by hand was a very costly, labor-intensive, and time-consuming process, so it was usually undertaken only by monks and priests seeking to preserve sacred music for the church. The few collections of secular (non-religious) music that are extant were commissioned and owned by wealthy aristocrats. Examples include the Squarcialupi Codex of Italian Trecento music and the Chantilly Codex of French Ars subtilior music.

The use of printing enabled sheet music to reproduced much more quickly and at a much lower cost than hand-copying music notation. This helped musical styles to spread to other cities and countries more quickly, and it also enabled music to be spread to more distant areas. Before the invention of music printing, a composer's music might only be known in the city she lived in and its surrounding towns, because only wealthy aristocrats would be able to afford to have hand copies made of her music. With music printing, though, a composer's music could be printed and sold at a relatively low cost to purchasers from a wide geographic area. As sheet music of major composer's pieces and songs began to be printed and distributed in a wider area, this enabled composers and listeners to hear new styles and forms of music. A German composer could buy songs written by an Italian or English composer, and an Italian composer could buy pieces written by Dutch composers and learn how they wrote music. This led to more blending of musical styles from different countries and regions.

The pioneer of modern music printing was Ottaviano Petrucci (born in Fossombrone in 1466 – died in 1539 in Venice), a printer and publisher who was able to secure a twenty-year monopoly on printed music in Venice during the 16th century. Venice was one of the major business and music centers during this period. His Harmonice Musices Odhecaton, a collection of chansons printed in 1501, is commonly misidentified as the first book of sheet music printed from movable type. That distinction belongs to the Roman printer Ulrich Han's Missale Romanum of 1476. Nevertheless, Petrucci's later work was extraordinary for the complexity of his white mensural notation and the smallness of his font. He printed the first book of polyphony (music with two or more independent melodic lines) using movable type. He also published numerous works by the most highly regarded composers of the Renaissance, including Josquin des Prez and Antoine Brumel. He flourished by focusing on Flemish works, rather than Italian, as they were very popular throughout Europe during the Renaissance music era. His printing shop used the triple-impression method, in which a sheet of paper was pressed three times. The first impression was the staff lines, the second the words, and the third the notes. This method produced very clean and readable results, although it was time-consuming and expensive.

Until the 18th century, the processes of formal composition and of the printing of music took place for the most part with the support of patronage from aristocracies and churches. In the mid-to-late 18th century, performers and composers such as Wolfgang Amadeus Mozart began to seek more commercial opportunities to market their music and performances to the general public. After Mozart's death, his wife (Constanze Weber) continued the process of commercialization of his music through an unprecedented series of memorial concerts, selling his manuscripts, and collaborating with her second husband, Georg Nissen, on a biography of Mozart.

In the 19th century, sheet-music publishers dominated the music industry. Before the invention of sound recording technologies, the main way for music lovers to hear new symphonies and opera arias (songs) was to buy the sheet music (often arranged for piano or for a small chamber music group) and perform the music in a living room, using friends who were amateur musicians and singers. In the United States, the music industry arose in tandem with the rise of " black face " minstrelsy. Blackface is a form of theatrical makeup used predominantly by non-black performers to represent a black person. The practice gained popularity during the 19th century and contributed to the spread of negative racial stereotypes of African-American people.

In the late part of the century the group of music publishers and songwriters which dominated popular music in the United States became known as Tin Pan Alley. The name originally referred to a specific place: West 28th Street between Fifth and Sixth Avenue in Manhattan, and a plaque (see below) on the sidewalk on 28th Street between Broadway and Sixth commemorates it. The start of Tin Pan Alley is usually dated to about 1885, when several 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 and radio 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 American popular music were upstaged by the rise of rock & roll.
