By the end of World War II, "mountaineer" string band music began to emerge. What is the more common name for this subgenre of country music?

When mandolinist, singer, and songwriter Bill Monroe joined forces with Lester Flatt and Earl Scruggs at the end of World War II, "mountaineer" string band music, better known as bluegrass, began to take shape. Introduced to Roy Acuff at the Grand Ole Opry, Bill Monroe would come to be known as the "Father of Bluegrass".
