20th Century. Bartok's Romanian Folk Dances, composed in 1915, are among his best-known works. They exist in multiple forms, since as well as several piano arrangements and a later orchestral version of his own there also exist arrangements by his contemporaries that were made with his consent. Today we can even access performances of the dances by Bart˘k himself; these recordings document varied repeats enriched by octave doublings to make a sort of "concert version" of the dances. Bart˘k expert L szl˘ Somfai brings order to the rich fund of sources, and in Henle's Urtext edition enters significant variants directly into the musical text itself. -the publisher
