This setting of String Trio wins the audience’s hearts with its airy lightness.
Krzysztof Penderecki was sometimes fond of returning to previously tested solutions. Sinfonietta is thus an orchestral version of his earlier piece, the String Trio. The larger performing forces made it possible to bring out all the contrasts of textures and tempi.
The composer uses his favourite intervals, including seconds and thirds, but also allows himself to get carried away by the cantilena of the solo violin. Some passages demonstrate close affinities with the opera Ubu Rex, composed at the same time, which at many places gives the music a grotesque character. The incessant recurrent oscillating motif based on repeated two- and three-note cells speeds the music up to a gallop – a technique characteristic of Penderecki’s late period.
