Obscuritas luminosa, lux obscura: Piece for six instruments and prerecorded electronic sounds
MetadataShow full item record
This piece is about light. Light as flux of photons. Light as flux of energy. Frequencies as colored light Light enveloped in darkness. Matter as condensed light. Light that cannot be seen. The following excerpt from an old Greek text of the 7 th century AD encapsulates the central idea of the piece: ...And as all things come from the One, from the mediation of the One, so all things are born from this One by adaptation.... There is one pitch (B), which as a single ultra-concentrated beam of light penetrates the vacuum, the silence. The instruments and the prerecorded electronics act like lenses and prisms that slowly change the color of this single B and magnify it to the neighboring pitch areas. Since this process is gradual, like wine fermentation, special attention is given to various subtle changes, in the micro-intervals and their beatings, attacks and dynamics, colors and textures. Once the magnifications of the single pitch expand to its partials, the fermentation process is accelerated and new dimensions open up that at some point incorporate even chance. The role of the electronics is to unify the instrumental fragments and thus to provide coherence through the piece. Although obscure at the beginning, progressively the electronics become the 7 th player in the ensemble, and after a certain point it develops in to an all-inclusive ocean, where the instruments float, like exotic fish. The electronics are based in various processing techniques programmed in Max/MSP, such as phase vocoding, infinite decay reverbs, variable delays and granular synthesis.
