Fluctus explores the movement of sound waves,their intrinsic tendency to propagate longitudinally and the process of abstraction relative to flow.The composition naturally induces listeners to dose their eyes in order to concentrate on the acoustic waves and perceive the undulating movement more intensely. Fluctus is the wave,shifting energy described by sound elements of different frequencies,intensity and duration.
The piece is composed of sounds of metal percussions, sinusoidal sounds and feedback sounds. The metal percussions,particularly rich in harmonic partials,were recorded using alternative and
immersive techniques to intensify the directional perception of the sound wave through the resonances,falls and audio tails pertaining to them. So the microphone is used as an actual
musical instrument. The incorporation of pure sinusoidal sounds triggers frequency beats and consequently accentuates the undulating movement of the sound material.The loudspeaker becomes an instrument along with the microphone,putting the percussion and sinusoidal sounds back into circulation by recording them in a feedback loop,thus making ali the sonic elements interdependent. In the acousmatic context, the sound waves of Fluctus become musical objects that give shape to
impalpable sound and are conducive to imaginary visions.
