A honky-tonk is both a bar that provides country music for the entertainment of its patrons and the style of music played in such establishments. It can also refer to the type of piano used to play such music. Bars of this kind are common in the South and Southwest United States. Many eminent country music artists, such as Jimmie Rodgers, Loretta Lynn, Patsy Cline, Ernest Tubb, Johnny Horton, and Merle Haggard, began their careers as amateur musicians in honky-tonks.
