In this piece I tried to explore relations between sound duration and the timbre of the violoncello. Chasing an approach to the temporal attributes that create our perception of repetition and continuity is sequences of sounds, I built-up multiple series emphasizing the asymmetry of the duration of sounds. With no reference but the tempo units for the individual tones’ duration, I created temporal transitions based on the harmonic evolution of the lowest note of the instrument. Considering this distribution of the structure of the overtones I created a resonating filtering process with the computer that emphasizes and diminishes certain higher harmonics. Using this process I tried to use the electronic processes in a way that would enrich the articulation of the instrument integrating them as part of the original sound.
