This work has four movements.
The first is slow. We can hear an unstable melody as the lead voice. Instruments that do not play the lead voice will serve to create timbre interferences and add colour to it.
The second movement is fast. It begins with a cadence played between violin I and viola I. Violin I ends the cadence and little by little the whole group appears. In a quick movement we can hear the melodic-rhythmic cells of the cadence, but now played and developed by the string quartet in different combinations.
The third movement is slow. As in the first, here the idea of a slow and unstable melody reappears. However, this time the texture is denser, there are many voices, both main and secondary voices, that create an overlap of sound planes.
Finally, the fourth and last movement is fast. As if it were a “coda” (final passage), we can hear elements of the three previous movements combined: fast cells that recall the second movement, as well as slower lines, as in the first and third movements.
