This three movement composition with the form close to sonata was written for the Warsaw Piano Quintet. The movements are contrasting. The first one is a free form of sonata allegro and features thematic dualism, develpoment and reprise. The second movement has a peaceful character. Each repetition is exposed to different variation regarding the rhythm, instrumentation as well as melodic line. The third movement is lively and full of tension.
The piece links achievements of the past with modern music. Composer synthesised such form creating measures as melodic, rhythm, instrumentation (colour), dynamics and agogic. He specifically explored polyphonic and variation techniques. The virtuoso piano part corresponds with the quartet, opposes or intervenes and sometimes complements the theme.
