Juan Sebastián Lach

In this installation, a computer generates harmonic textures based on the sounds that occur in the space, using an analysis that metaphorically imitates the “sensorial ether” where perception takes place and from which it extracts and sets in motion certain harmonic qualities inherent in sounds, in the same way that the process of understanding infers abstract forms on the basis of sensory data (aesthesis).

First shown at Transitio in 2011 with a quadraphonic arrangement, Ahí estése… has been adapted to the Space for Sonorous Experimentation in a way that extends the distribution of the aural arrangement. This involves the number and specific locations of the speakers in the room and the microphone that picks up the sounds produced there in real time, whether by the audience, invited musicians or the installation itself, and which cause feedback that constantly changes the resulting sound. In the first version, these results were achieved by programing 4 types of “behaviors”, such as timbre, texture, rhythm and “orchestration”, each capable of a wide range of variability (tempo, density, character of rhythm and timbre). For this new version the composer developed a larger number of algorithmic behaviors, enabling new possibilities for generation of sound.
