When did Bluegrass begin?

Bluegrass as a style developed during the mid 1940s. Because of war rationing, recording was limited during this time, and the best we can say is that bluegrass was not played before World War II, and it was being played after. As with any musical genre, no one person can claim to have "invented" it. Rather, bluegrass is an amalgam of old-time music, blues, 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 now known as "Scruggs style," is pointed to as the key moment in the development of this genre. Monroe's 1945-48 band, which featured banjo player Earl Scruggs, singer/guitarist Lester Flatt, fiddler Chubby Wise and bassist Howard Watts, aka "Cedric Rainwater," created the definitive sound and instrumental configuration that remains a model to this day.

By some arguments, as long as the Blue Grass Boys were the only band playing this music, it was just their unique style; it could not be considered a musical genre until other bands began performing the same style. In 1947 the Stanley Brothers recorded the traditional song "Molly and Tenbrooks" in the Blue Grass Boys' style, and this could also be pointed to as the beginning of bluegrass as a genre.

It is important to note that bluegrass is not and never was a folk music under a strict definition, however the topical and narrative themes of many bluegrass songs are highly reminiscent of "folk music". In fact many songs that are widely considered to be "bluegrass" are older works legitimately classified as "folk" or "old-time" performed in a "bluegrass" style. From its earliest days to today, bluegrass has been recorded and performed by professional musicians. Although amateur bluegrass musicians and trends such as "parking lot picking" are too important to be ignored, it is professional musicians who have set the direction of the genre. While bluegrass is not a folk music in the strictest sense, the interplay between bluegrass music and other folk forms has been studied. Folklorist Dr. Neil Rosenberg, for example, shows that most devoted bluegrass fans and musicians are familiar with traditional folk songs and old-time music and that these songs are often played at shows and festivals.
