The music of Oregon reflects the diverse array of styles present in the music of the United States, from Native American music to the contemporary genres of rock and roll, country, rhythm and blues, jazz, pop, electronic music, and hip hop. However, throughout most of its history, the state has been relatively isolated from the cultural forces shaping American music. Much of modern popular music traces its roots to the emergence in the late 19th century of African American blues and the growth of gospel music in the 1920s. African American musicians borrowed elements of European and Indigenous musics to create new American forms. As Oregon's population was more homogeneous and more white than the United States as a whole, the state did not play a significant role in this history.
