Pulsar-Mimesis

I. Pulsation-Magnetic Fields

II. Gravity-Density

III. Movement-Expansion

The Mimesis, from classical culture, is the representation of nature as essential purpose of art, drawing analogies and using representative features of the original. This work generates from this representation qualities and characteristics of Pulsar (acronym for Pulsating Star) a neutron star that emits radiation periodically and has very particular characteristics. From each of these features, an idea or materials specific sound is generated and will be developed in each movement.

In this way, the first movement (Pulsation-Magnetic Fields) is written from a pulsation (mimesis of stellar pulsation) projected throughout the movement with a spectral harmony (mimesis of the magnetic field).

The second (Gravity-Density) to represent the external weightlessness of pulsar, is generated from overlapping harmonic atmospheres to a "Cantus firmus" extracted from the "Llibre Vermell" (Middle Ages), in particular from "Stella Splendens" and to represent density, appear very dense rhythmic and harmonic textures with microtonality, especially working the concepts of harmonic field and micropolyphony.

Neutron stars spin so fast that expand on your equator, reaching forming stardust because of this breakneck speed. The combination of enormous density with intense magnetic field causes the particles are close to the star from the outside, are accelerated to extreme speeds. The third movement (Movement-Expansion) is the representation of these concepts through fragmentation and reconstruction of all materials of the work from the rhythmic motion and temporal, and through the connection of the motivic cells derived from previous movements, as well as rhythmic elements that will accelerate gradually to extreme speeds. All this leads to a final chaotic and violent movement as a great reexposure-deconstruction of all rhythmic, harmonic, sonorous and timbral elements of the work.

This work has been written for "WASBE 2015 Conference" in San Jose (California, USA) and is dedicated to Maido Navajas, Arnau Pascual and Martina Pascual.
