4. List and describe three styles of music composition that developed
during the 20th century.

(Please paraphrase it because I got this from Wikipedia)



Country music, hip hop, and jazz

Explanation:

Country music: Country music, once known as Country and Western music, is a popular musical form developed in the southern United States, with roots in traditional folk music, spirituals, and the blues.

Hip hop: Hip hop music is traditionally composed of two main elements: rapping (also known as MC'ing) and DJing, and arose when DJs began isolating and repeating the percussion break from funk or disco songs.

Jazz: Jazz is a musical art form characterized by blue notes, syncopation, swing, call and response, polyrhythms, and improvisation. It has been called the first original art form to develop in the United States of America and partakes of both popular and classical musics.
