Where does bluegrass come from?

The term 'bluegrass' is widely accepted as having been coined by the noted folklorist and music researcher Bill C. Malone, who used it in his 1962 article "Country Music in West Virginia". In early 1948, radio host and entertainer Ted Daffan created the term 'The Foot Hill Boys', which was later changed to 'Blue Grass Boys' or 'Bluegrass Boys' because of the group's regular live performances at the Renfro Valley Barn Dance, near Renfro Valley, Kentucky, just over the border from Flatwoods. It is known that Monroe used several terms to describe his music style, including "Kentucky mountain", "high lonesome", and "the new sound". Monroe said he came to the term 'bluegrass' for the genre when asked by a radio announcer where he was from, and he replied, "Why, I'm from the Bluegrass State". According to his son James, Monroe originally wanted the new name to be "Green Grass Boys", but another group already had that name, and one radio station had been calling the Blue Grass Boys the "Bluegrass Boys" for at least a year before Monroe made the name change official. Bill C. Malone first heard Monroe's music on the radio in 1947, and was deeply moved by it, stating, "I heard something wonderful, something I had never heard before".
