Corrosión is a piece for orchestra that explores different representations of multiphonic material, in particular, a series of these produced by the double basses and amplified by the orchestral device. The observation and analysis of this type of material gradually revealed the parametric guidelines necessary for the construction of instrumental complexes capable of recreating their constitutive characteristics. The textural designs were basically developed from an acoustic-temporal envelope model that masks the attacks and decays of each sound and produces smooth formants, as opposed to the roughness typical of multiphonics.
On the other hand, while there is a permanent dialogue between the technical imagination that is put into play in writing and the concrete results that emerge from it, a large part of the compositional process remains associated with the field of intuition, so that the The work as a whole is finally a particular expression of the various decisions made throughout that course, something like a log of the dialectic between the sound material and the medium through which it is expressed. In other words, it is a constant search for meaning, and at the same time, in every aspect, a central part of an aesthetic.
