Although much of the music of "The Bartered Bride" is folk-like, the only significant use of authentic folk material is in the act 2 furiant, with a few other occasional glimpses of basic Czech folk melodies. The "Czechness" of the music is further illustrated by the closeness to Czech dance rhythms of many individual numbers. Smetana's diary indicates that he was trying to give the music "a popular character, because the plot [...] is taken from village life and demands a national treatment." According to his biographer John Clapham, Smetana "certainly felt the pulse of the peasantry and knew how to express this in music, yet inevitably he added something of himself." Historian Harold Schonberg argues that "the exoticisms of the Bohemian musical language were not in the Western musical consciousness until Smetana appeared." Smetana's musical language is, on the whole, one of happiness, expressing joy, dancing and festivals.
