The title Fantasia reflects the free use of the different formal resources used. We can therefore recognise the Variation, the Fugue and the structural elements of the Sonata form that are essential in structuring a work of certain complexity.
This work is a small poem with a simple and cantabile language, in which all instruments have the same level of prominence.
The Miniatures are small pieces for small groups (from duets, trios and quartets to groups of eleven players) which explore the possibilities of the performers from the perspective of sound rather than technique or virtuosity.
The Prelude and Dance follows a typical structure of Frederic Monpou, and the Finale closes the work.
The “fantasy” concept includes that of a movement-less piece, with a very free format that is playful in its use of contrasts, combining this initial theme with more dynamic fragments. In spite of this thematic reappearance, the work does not correspond to the rondo form, but the formal freedom is the one that commands.
