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.
In his String Trio No. 1 (1956) Lluís Benejam plays with the sounds of two violins and a viola from a classical premise yet with a modern spirit.
The Prelude and Dance follows a typical structure of Frederic Monpou, and the Finale closes the work.
