This work is bipartite; an introductory Andante and an Allegretto. The theme to be varied is an original theme by Rossini. As with other chamber works, “variations” refer both to the formal structure and to the technique of instrumental elaboration. The Allegretto in particular is divided into regular sections of eight repeated measures, in which the melody is given in turn to each instrument, accompanied by the others. Always recognizable, the melodic line is varied according to the idiomatic characheristics of the instrument.
