Bluegrass was pioneered by Bill Monroe, a mandolin player in the 1930s, who built on the Old Time Music tradition. It was developed around the same time that African-American jazz musicians developed bebop, and some people considered it "white jazz." Unlike Old Time Music, where everyone was welcomed in the performing of the music, bluegrass showcased professional musicians possessing a high-level of skill and technique. Bluegrass relied on the advent of technology (microphones, radio, and recordings) to gain popularity throughout the country. Bluegrass carried the sounds and subject matter of Old Time Music, but had the feel of something hard-driving and contemporary. This clip provides a glimpse at the impact of the banjo on Bluegrass style and history. Discussion questions are provided to support the video.
