that what generally passed as Hungarian folk music was actually gypsy music arranged according to conventional Central European standards. With his friend the Hungarian composer Zoltn Kodly, Bartk systematically collected and analysed Hungarian and other folk music, a collaboration that resulted in 12 volumes of folk songs. Bartk rarely incorporated folk songs into his compositions; rather, he assimilated into a powerful personal style the scales and melodic contours and the driving, often asymmetrical rhythms of Balkan and Hungarian folk music. His music always has a tonal centre, but this is usually established in personal, only partially traditional ways. The six-volume Mikrokosmos (1935), consisting of 150 progressively graded piano pieces, constitutes a summary of his development, as do his six string quartets, considered among the most important string quartets after those of Ludwig van Beethoven.
