Music and lit crit

Just like in literary theory there have been times when theorists/authors have not cared about previous authors at all or they have only cared about previous authors and historical context, music has gone through similar phases. During the 19th century and early 20th century, musicians played music by Mozart (1756-1791), Bach (1685-1750), Palestrina (1400s), and Perotin (1100s) all in the same style, even though the composers wrote in drastically different styles and they were meant to be played very differently. In the second half of the 20th century, musicians started trying to pay more attention to what the composer of each piece would have intended, and learn more about the historical context of the music. This then affected the performances and the style in which the musicians would play the different pieces. Like in literary theory, musical performance practice has changed a lot over time based on politics, world events, and random theorists writing exciting articles and books.
