Composed in 1915, the Sonatina is based on Romanian folk melodies collected by Béla Bartók during his ethnomusicological fieldwork. Rather than inventing folk-style themes, Bartók directly transformed authentic traditional material into concert music, preserving its rhythmic and modal character. The first movement, Bagpipers, reflects the sound world of traditional folk instruments through drone effects, modal harmony, and repetitive rhythmic figures. This piece exemplifies Bartók’s approach to integrating folk music into a modern compositional framework, combining scholarly research with creative transformation. It occupies an important place in his piano output as a bridge between folk tradition and early twentieth-century modernism.
