O som sob a regência da Semiótica Social Multimodal: uma proposta de análise no perfil do TikTok Fatos Curiosos com Antonio Miranda.

During the coronavirus pandemic, social media has played an important role in combating misinformation. It was also during this period that Brazil became the third TikTok consumer market in the world. In this panorama, the profile Fatos Curiosos com Antonio Miranda stands out, created in 2020 by student and tiktoker Antonio Miranda. Currently with 1.6 million followers and 13.5 million likes, the young man transmits scientific knowledge in a light and creative way in his videos. In this article, is investigated how the sound aspects instantiated in the most liked and commented video on Antonio's profile contribute to communicating, in a clear and accessible way, supposedly complex content, for the purposes of popularizing science in the digital environment. To this end, the theoretical-methodological framework proposed is that of Multimodal Social Semiotics, with regard to the qualities of sound and voice (VAN LEEUWEN, 1999). The main results found demonstrate that the sound resources instantiated in the vignette contribute to building an atmosphere of humor, lightness and relaxation; while the qualities of the voice fulfill the role of transmitting credibility, emphasizing key words and providing fluidity in understanding the explanation given by Antonio Miranda.
