Assuming a hommage to Gérard Grisey (founder of the spectral style), the begining of his Prologue for solo viola originates a spiral of musical gestures. A Propos d´un son was planned in a circular form, generating layers that overlap and autonomize themselves. These start in the gestures that get wider and wider, as well as in the melodical materials that come from the viola part, generating sound land- scapes that develop and establish themselves in the electronics. Both elements have a point of contact through the use of microtones, which creates a harmonic percep- tion that uniformizes all the existing counterpoint. This way, a simple sound creates a kaleidoscope of perceptions and auditions that refers to the own internal life of that original sound.
