Every thing that sounds both attacks and builds the adolescent. It represents one of the devices used by violence in the course of puberty : now adestructive one on the puberty side and, rather, an elaborative one when on the side of the adolescens process. Being a stamp of the adolescent space, a seat for group identifications, a containin and protecting envelope enabling the adolescent to be safely confronted to the threat of its piberty fantasies, everthing higt-sounding expresses violence at adolescence whilst shaping it at same time.
