Here is a nice video of how the Father of Bluegrass, Mr Bill Monroe shows us how it is done. Notice the song starts in 3/4 time and progresses to 4/4 time. Each bluegrass banjo player should put this in their repertoire of songs.
When I first got into bluegrass music, I couldn’t really appreciate this song as it sounded kind of “real hillbilly” but now, I regard it as one of the best songs that Bill Monroe ever wrote. The high lonesome sound is very common to the bluegrass genre of music. WOW!! I hope you enjoy it and learn how to play it. Let me know if you want me to teach you this one.
