Karol Plicka was an important musician and composer. He recorded folk songs immediately after hearing them in musical notation to preserve them for future generations. Similarly, he records and interprets traditions associated with dance, folk song and local stories that vary from region to region in his film The Eternal Song. The short documentary presents merry-making in Slovak and Czech regions that are changing with the coming modernization and transformation of musical records.
