The score is composed using a method I’ve named Nn (nomen nescio), where the overlay of the structure of Niels Bohr’s atomic model onto the Bösendorfer Imperial 290 piano model assigns a note to each element of the periodic table. I performed the sequence of elements present in the chemical formulas that describe the process of chlorophyll photosynthesis, recreating on the computer the extension over the 97 keys of the Bösendorfer piano. The resulting score was then inserted into a c-sound programming environment that manages pre-samplings, evolving them to a climax that becomes a metaphor for biological growth in the work.
The resulting track, recorded in its evolution up to the buffer overload limit, accompanies a concrete sound sample, namely the nighttime recording in the courtyard of via Genova 17, capturing the sounds of activity from the adjacent factory.
The increasing climax generated by the program lies on this sound bed, articulating into 4 variations of the algorithmic process.
