ブルーグラス・ミュージック
Bluegrass music is a genre of American roots music that developed in the 1940s in the United States Appalachian region.1 The genre derives its name from the band Bill Monroe and the Blue Grass Boys.2 Unlike mainstream country music, bluegrass is traditionally played on acoustic stringed instruments. Bluegrass has roots in traditional English, Scottish and Irish ballads and dance tunes, and in traditional African-American blues and jazz ーwikipedia バンジョーで演奏される
