摘要：The focus of this work is the operation of visual and audio signs in an urban ambience of entertainment, particularly the arragement of the interpretant of these signs in the luminous and cathartic output of vídeo presentations. The semiotic concept of diagrammatic reasoning is used to describe and analyze the apparitions of a clown character in an electronic music show of the British duo The Chemical Brothers, selected corpus for the study. The analyses cover the uses and the track of images and sounds at the moment the action takes place, with mask and trance being mobilized to exert hedonist, phantasmagoric, carnivalesque and ritualistic influence on the audience. The acting clown tends to produce interpretants, initially of na emotional and, subsequently, of an energetic nature, so as to incisively establish identity links with the audience. The developments of the character’s apparitions (which is inserted into the performance in different ways to yield persuasive messages) are analyzed along with the effects resulting from the conjunction between sound and image which propagates in a synchronic, ambivalent and profuse manner, amid a crowd, an urban landscape and a playful phenomenon. A spiral shape guide was prepared to support the analysis and enable to infer about the work of the interpretant signs from the VJing, a kind of semeiosis typical of the videojockey’s action in this sort of event. Identity is then impregnated and so are mnemonic effects on the metropolitan cultures and habits, in the libertarian and effervescent nature of the party, on the emotion fruition reached by the audience.
