Liturgia fractal is a cycle of five string quartets in which each quartet is based on a different fractal model. Working with a fractal model, as something of an allegory of the way waves move, is based on the concept of a cycle as a “natural entity”. The combination of the idea of self-similarity (fractal) with that of spreading-out (wave) reflects the search for a sound which develops organically, as if it were just another part of nature.
The cycle consists of altogether five quartets, but it is also possible to perform two or three in various combinations without losing the balance achieved within the overall collection. One of the quartets, Arborescencias, can even be interpreted as a single, independent work.
Ondulado tiempo sonoro..., the first quartet, functions as a seed for the rest. This work presents the most important musical material and parameters around which the rest of the collection revolves.
Each quartet adds new material to that which was used before, and this material then appears in the following quartets as well. In this way, each of the pieces seems like a sort of “transformed overall sum” of the one before.
The cycle Liturgia fractal was commissioned for Quatuor Diotima by the festival Musica Strasbourg, the Casa da Música in Porto and Spain’s CDMC (Centro para la Difusión de la Música Contemporánea). (Alberto Posadas)
