Bluegrass music is a form of American roots music, and is a sub-genre of country music. It has roots in Scottish, English, Welsh and Irish traditional music. Bluegrass was inspired by the music of immigrants from the United Kingdom and Ireland (particularly the Scotch-Irish immigrants in Appalachia), and African-Americans, particularly through genres such as jazz and blues. In bluegrass, as in some forms of jazz, one or more instruments each takes its turn playing the melody and improvising around it, while the others perform accompaniment; this is especially typified in tunes called breakdowns. This is in contrast to old-time music, in which all instruments play the melody together or one instrument carries the lead throughout while the others provide accompaniment. Traditional bluegrass is typically based on a small set of acoustic stringed instruments including mandolin, acoustic guitar, banjo, fiddle, resonator guitar and upright bass, with or without vocals.
Bluegrass as a style developed during the mid-1940s. Because of war rationing, recording was limited during that time, and it would be most accurate to say that bluegrass was played some time after World War II, but no earlier. As with any musical genre, no one person can claim to have invented it. Rather, bluegrass is an amalgam of old-time music, country, ragtime and jazz. Nevertheless, bluegrass's beginnings can be traced to one band. Today Bill Monroe is referred to as the founding father of bluegrass music; the bluegrass style was named for his band, the Blue Grass Boys, formed in 1939. The 1945 addition of banjo player Earl Scruggs, who played with a three-finger roll originally developed by Snuffy Jenkins and others but now almost universally known as Scruggs style, is considered the key moment in the development of this genre. (Jenkins, in interviews, has said he learned it from Rex Brooks and Smith Hammett in the 1920s.)
