The piece Chamber Music No. 5 'The Four Seasons' was written in 1981, on the initiative of Zygmunt Krauze, with a view of a first performance in Paris in January 1982. The plan did not materialize due to the imposition of martial law in Poland in December 1981. In 1981-84 I introduced minor alterations to the piece. It was premiered in its new shape after quite a while, on 1 April 1989, by the'Encores Chamber Orchestra under Wojciech Michniewski at the 'Poznań Spring' Festival. The work's individual sections (Spring, Summer, Autumn, Winter) are in stark contrast to each other. They were written in the corresponding seasons of the year and are a reflection of my emotional and spiritual state rather than a musical illustration. The musical material was subjected here and there to a fairly strict treatment. By and large no rigours were applied in relation to metre or rhythm. This gives the performers a sense of freedom, which in effect should produce an expected consistency. The piece is dedicated to Krzysztof Droba.
