Who came first in the history of blugrass?

Bluegrass music emerged in the 1940s, primarily credited to Bill Monroe, who is often referred to as the "Father of Bluegrass." Monroe's band, the Blue Grass Boys, helped define the genre's distinctive sound, characterized by its use of acoustic instruments like the mandolin, banjo, and fiddle. While other musicians contributed to its development, Monroe's influence and innovations were pivotal in establishing bluegrass as a distinct musical style.
