he rateliai round dances have long been a very important part of Lithuanian folk culture, traditionally performed without instrumental accompaniment. Since the 19th century, however, fiddle, basetle, lamzdeliai and kanklės came to accompany the dances, while modern groups also incorporate bandoneon, accordion, concertina, mandolin, balalaika, clarinet, cornet, guitar and harmonica. During the Soviet era, dance ensembles used box kanklės and a modified clarinet called the birbynės; although the Soviet ensembles were ostensibly folk-based, they were modernized and sanitized and used harmonized and denatured forms of traditional styles.
