Stereotypes exist in every facet of life, and the orchestra world is no exception. While previous research has shown distinctive perceptions of musicians in the brass section versus other sections of the orchestra, my own investigation discovers the unique differences in stereotypes between each brass instrument aside from some general overlap of traits. Origins of these stereotypes are explained by several factors: the historical function of each brass instrument, the development of their roles in orchestral music throughout history, interactions between the brass section in both a musical and social context, instrument selection, and gender inequality. Interviews were conducted with four professional brass musicians with a diversity of backgrounds and experience in order to get a better sense of their personal perceptions of the aforementioned factors, and how their personalities may or may not connect with the stereotypes.
