visible sound and light installation
duration 30 min. looped
Polyphotony, though largely conceived as a musical piece, is not audible. Instead of using sound as the piece's main material, Triana employs light to manipulate parameters commonly assigned to music, such as time, frequency, rhythm, etc.
Evoking musical instruments, the installation includes five sculptures, each composed of a string, speaker, and tuning peg. An audio signal from a loudspeaker excites the string, and a simple sound wave is made visible on the string. This sound wave operates as a canvas in which light waves, acting as the main material for the piece, get reflected.
The title Polyphotony references the musical term polyphony, which means multiple voices, and photo—the prefix that alludes to light. Individual light waves are isolated and treated as independent musical voices.
The composition departs from a state of simplicity—a single light wave/voice—and gets denser, gradually and slowly. As the piece unfolds, new light voices are incorporated, generating a complex process of interference and interaction among the waves. Once the piece has reached its maximum level of complexity, it falls back to the beginning, repeating as a seamless loop. All five sculptures act like members of a musical ensemble, performing the same piece at different frequencies—thus, synchronizing periodically, by groups, or in tutti..
