The relationship with the classical tradition, required by the title Divertimento is somewhat perverse. The piece has an intimate instrumentation, although the title flute, whose part is realised by a single player comes in two varieties: big and small (piccolo), and the only wind instrument multiplied to two is the clarinet. For that matter, the percussion is very rich for light music (in the eighteenth-century meaning of the term) with cymbals, with tom-toms, snare drum, tambourine, triangle, castanets, wood block (Blocco di legno), bells, tam-tam and xylophone. There are strings and a harp in an intimate, solo ensemble lineup (4-2-1-1), with frequent divisi in the violins. Formally, the piece is one movement, but its internal structure shows the layout of ABA1, which is marked not only by tempo changes: Allegretto (Quasi Andantino) - Piu andante - Tempo I (allegretto), but also by the slightly different nature of the miniscule part B. The whole, as already been said, is dominated by a bouncy little theme, based in its original form on only three, irregularly-repeating moving notes, actually jumping in a steady, sixteenth note swinging motion. Already this theme funny at its core, harshly diatonic, contrasts with the harmonic base - provokes us to exclaim typical Kisielewski! [M. Gąsiorowska, Kisielewski, PWM 2011]
