Introdução: determinar mudanças no grau de adução dos vincos vocais e características de ressonâncias em cantores, posterior à implementação de uma sequência de aquecimento vocal fisiológico. Materiais e métodos: se aplicaram medidas de análise acústico e eletroglotografia a 11 cantores, realizando quatro tarefas fonatórias antes e depois da implementação de uma sequência de três exercícios de Trato Vocal Semiocluído (mão sobre boca, fonação em tubos de ressonância e “Y-Buzz”), cada um com três tarefas fonatórias (fonação em tom e intensidade cómodas, variação de tom com glissandos de terceira e quinta nota de escalas maiores, variação da intensidade vocal com estratégia de Messa di Voci). Estudo experimental, com análise estatístico descritivo, e aplicação da prova não paramétrica Wilcoxon para o caso do Cepstrum. Resultados: mudanças positivas a curto ou mediano prazo em todas as medidas aplicadas. Todos os sujeitos aumentaram a ensação de voz ressonante, apresentaram melhoria na qualidade vocal cantada, voz com mínimo
stress de impacto dos vincos vocais e maior projeção, aspetos refletidos nas correlações positivas entre Cociente de Contato, Medidas de perturbação, ltas e Cepstrum. Discussão: o aquecimento vocal fisiológico é uma ferramenta que contribui a melhorar e cuidar o instrumento de trabalho de cantantes, a energia acústica no trato vocal melhora depois da sequência de aquecimento vocal fisiológico, observando um efeito imediato e cada vez maior a longo prazo.
