ALBERTO POSADAS (b.1967): Liturgia fractal for String Quartet.
Catalogue Number: 08L115
Description: The analogy of fractal mathematics as applied to music is not a new idea, either used figuratively and descriptively or more literally as the structural basis for various kinds of formal procedures. Posadas' cycle of quartets falls into the latter category insofar as various mathematical constructs are used to generate overtone series, the distribution of pitch classes, the durations of musical events, and so on. Can a listener 'hear' the specific mathematical models on which the music is based? Arguably not. But in the obsessive piling-on of detail on top of detail, the scurrying motion of elaborate layers of sonic texture, it is certainly possible to imagine a relationship between the microscopically repeating patterning of fractal geometry or the chaotic yet statistically predetermined motion of particles in Brownian Motion and the music's high-energy flutterings and squealings. Especially in the dendritic efflorescences of the fourth piece in the cycle it is very easy to perceive a precisely ordered musical analogy of natural, organic growth processes, and the composer's timbral palette is broad and imaginative, leading to many intriguing sonic textures along the way. Quatuor Diotima.
