Towards new on-line cultural possibilities

In this paper, we show how the practice of buying CDs surreptitiously conditions our musical activities, and how the practice of classifying a priori, making changes one at a time, structured by buying and the notion of genre, will disappear, as develops an ad hoc organization of auditory samples, centered on prototypes and similarity. This movement is a proof of the loss of importance of the instantiation of CD marketing categories. Thus appears similarity-based calculus, acting on considerable masses of samples, which continuously change the balance of the man-machine dialogue, in an appeal started again and again to compare information. We also show how some artistic creations which rely heavily on computers, especially in the domain of inter-media theater, proceed in the same way, masking instantiation and developing the calculation of the similarity of the comedian´s expressive faces. Art and culture are linked in processes that take advantage of their massive digitalization.
