The political and economic instability in many Latin American countries have been deeply affecting the life of its inhabitants for decades. Support for artistic activities has usually been postponed to solve urgent social problems. In spite of that, the development in the region of the electronic arts in general and the electroacoustic music in particular, is really astounding. To name but a few examples: Mauricio Kagel composed eight electroacoustic studies in Argentina between 1950 and 1953, according to Hugh Davies’ International Electronic Music Catalog. José Vicente Asuar in Chile, Joaquín Orellana in Guatemala, Reginaldo Carvalho in Brazil, Horacio Vaggione in Argentina, Héctor Quintanar in Mexico and Juan Blanco in Cuba are only some of the many names in the ocean of electroacoustic music creativity that has always been Latin America.

Following the serial character of the composition concept, the titles were published consecutively as EPs. For the visual translation and presentation as a live performance and audiovisual installation, the sinusoidal waveform is abstracted along the album convention. Following parameterized principles, twelve visual embodiments of this basic shape arise. The increasing complexity is now visible and the prevailing simplicity at the beginning inverted by the end. This evolving aesthetic is punctuated with a grid, that divides the base with the value of the sample number.

This is a concert (or an installation) focusing on recovering and make known part of the history of electroacoustic music from Latin American.

Following the formal rules of dodecaphony, for Zwölftonform twelve consecutive titles are composed exclusively with twelve consecutive frequencies. The basic structure for each title is made by up to twelve different sound samples from a generated sine waveform. Built on this basis, these arrangements reference and illustrate especially over time the complexity and increasing compression of the original shape.
