Where did country music begin?
It began in the 19th centry (:
That's a loaded question depending on who you ask. But country music is born from Appalachian Music, Appalachian music came from Ireland, Irish music is European, and before that, you get music period. What most people would consider country music has been around since the birth of America. Buffalo Gal and songs like that have been around for a long time.
The difference between bluegrass and country music is in its roots. Bluegrass has its roots in the traditional music of Irish, Scottish, Welch and English music, but it is considered a sub-genre of country music. Country music has roots in the southern U.S. and is taken from American folk Western music.
