Objective: This study evaluated the effects of acute administration of oxytocin in the musical performance anxiety in professional singers, having the Test of Public Singing Simulation as parameter.

Method: We conducted a double-blind crossover randomized placebo-controlled clinical trial, with 50 professional male singers as subjects, of whom 16% were erudite singers and 84% were music contemporary commercial singers, with an average period of experience of 10.96 years. All singers self-administered a singular dose of 24UI of oxytocin or placebo via a nasal spray, in different sessions, according to the group they were placed with. After 51 minutes of oxytocin or placebo administration, the Test of Public Singing Simulation was performed, which consisted of an acapella musical interpretation of a song of the singer’s choice for 4 minutes in a controlled environment. Measures of mood indicators were analyzed, as well as performance and vocal symptoms, with self-assessment scales and analysis of voice acoustic measurements using Multi-Dimensional Voice Program Advanced software at six stages. An analysis of the ANOVA 2x2
Results: Was demonstrated an effect in the oxytocin treatment when compared with placebo, improving the in stages during and after performance. There were no changes in mood indicators, vocal signs, and symptoms, or in vocal acoustic measures. Sequence and period effect were not evident for the reviewed measures.

Conclusion: In conclusion, the oxytocin had an anxiolytic effect, emphasizing an improvement in self-evaluation concerning performance with no adverse reaction in terms of voice signs and symptoms and vocal acoustic measures.
