The music in America today is part of a continuum that reaches back to the Indigenous peoples and stretches across the Atlantic Ocean to the Old World. Music, instruments, and songs tell the story of the ordinary and extraordinary people who have populated the United States and propelled it into the 21st century. The genres of music explored through Ballad of America include traditional folk songs, fiddle tunes, ballads (both Old and New World), sea shanties, railroad and cowboy songs, Appalachian, ragtime, spirituals, work songs, minstrel, blues, jazz, jug band, rhythm and blues, old-time, country and western, Cajun, bluegrass, and rock & roll.
