This dissertation considers the influence of modern recording technology on trumpet pedagogy. The research specifically looks at the listening habits of students and the sources they use for concepts of sound. It is hypothesized that students are attending less live performances and using recordings as their fundamental basis for a concept of sound. How much of commercially released recordings have been manipulated by recording technology? Can the listener identify when these edits have taken place? How does this effect student motivation and outcome? A survey that addresses the listening habits of students was created by the author and sent to four major universities around the United States to collect data. In addition, the author gave personal interviews to leading professionals in the fields of recording, performing, teaching, and composing. The results show that students are attending less live performances and referencing digital, online recordings more and more. The author also took part in a recording project to demonstrate the influence of digital recording technology on trumpet pedagogy. This research has led the author to reevaluate his expectations of the necessary curriculum for college music students. Additional suggestions for teachers are included to help address potential negative ramifications of the trends discovered in this research.
