This piece was composed at the commission of trombonist Juliusz Pietrachowicz. It consists of three contrasting movements. The first one draws on sonata allegro with two theme groups. The exposition is followed by the virtuoso solo cadence and the ending. The second movement is similar to A-B-A’ structured aria.
The middle B part is in rhythmic and energetic contrast wit A parts. The third movement has a form of A-B-A’-C-A”-B” rondo referring to Kurpie folk music, very individual, without citations however, just having the folk character.
The means of artistic expression are moderately modern with high demands for the artist. The second version of this piece was composed for trombone and wind band (1974).
