It is important to understand the deep meaning of initial It is important to understand the deep meaning of initial performance. We have known performance as a transitional performance. We have known performance as a transitional process from mental to physical reality. This is a transition process from mental to physical reality. This is a transition from the score to the acoustical realization, to be archived on from the score to the acoustical realization, to be archived on sound media such as a CD. Following the valid doctrine—as sound media such as a CD. Following the valid doctrine—as preconized by Paul Valpreconized by Paul Valééry and Theodor W. Adorno—the ry and Theodor W. Adorno—the performance is an integral part of the work of artperformance is an integral part of the work of art, and this , and this means that, in the sense of communication theory of art as means that, in the sense of communication theory of art as described by Jean Molino, performance is part of the semiosis described by Jean Molino, performance is part of the semiosis of the work, its meaning is not complete except when it is of the work, its meaning is not complete except when it is performed. performed.

Put it the other way round: The mental score conveys a part Put it the other way round: The mental score conveys a part but not the whole content, and only via performance can we but not the whole content, and only via performance can we complete the work’s semiosis. Performance englobes a kind complete the work’s semiosis. Performance englobes a kind of usage of the mental score sign by a performer. More of usage of the mental score sign by a performer. More specifically, those signs whose content are not only specifically, those signs whose content are not only instantiated but substantially depend on the user are the well-instantiated but substantially depend on the user are the well-known shifters. Performance of a mental score is such a shift known shifters. Performance of a mental score is such a shift from lexicality to full-fledged meaning, since the pure score from lexicality to full-fledged meaning, since the pure score is essentially less than the work of art. In other words, is essentially less than the work of art. In other words, performance is a shifter characteristic of the score semantics. performance is a shifter characteristic of the score semantics.
Production of full-fledged meaning is only possible by means Production of full-fledged meaning is only possible by means of performance, and this adds a semantic aspect to the sign of performance, and this adds a semantic aspect to the sign
