This research aims to know the relationship between the variables teachers' pedagogical management and instrumental performance in students from an Artistic Higher Education School. It is a descriptive and correlational research that seeks to find the relationship between both variables. The sample of the study consisted of 30 students of the symphonic band to whom two instruments were applied: a questionnaire for pedagogical management and a checklist for instrumental performance in the symphonic band. The results of the research showed when applying the Spearman's correlation formula a significance level of 5%, with a significant correlation of Rho = 0.843. Based on that, it is determined that a very good pedagogical management of teachers produces a very good instrumental performance of the symphonic band in the population under study. Specifically, when analyzing the results of the specific cognitive and procedural competences of the teacher in relation to the instrumental performance, a moderate correlation was found; when analyzing attitudinal and teaching competences of the teacher in relation to the instrumental performance, a good correlation was found. It was concluded that there is a significant correlation between the variables teachers' pedagogical management and instrumental performance.
