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.
