Bluegrass

Bluegrass is a form of American roots music that originated in the Appalachian region of the United States in the 1940s. It is characterized by its distinct instrumentation, fast tempos, and vocal harmonies. The music has its roots in the traditional string band music of the Appalachians, and combines elements of blues, jazz, and country music. Bluegrass is most often associated with the genre of country music, and is played on acoustic stringed instruments, including the banjo, guitar, mandolin, and fiddle. The style is also commonly associated with a certain "high lonesome" sound, which is a combination of a strong vocal harmony and a unique picking style on stringed instruments. The style has had a significant influence on other genres, including rock, pop, and folk.
