As teaching and learning experiences broaden to include more technological innovations, methods of instruction and resource flexibility are becoming increasingly important for educators and students. Open educational resources (OER) have gained international appeal for such flexibility, and post-secondary institutions are at the forefront of creating access to them. Although research related to OER has increased, few researchers have focused on OER in music instruction. In my cross-sectional survey of music faculty in the United States (N = 409), I found that music faculty were generally unaware of OER although most participants would consider adopting an open textbook for a course. Motivating factors for adoption included ease of use and decreased costs for students, whereas time and financial support would be necessary for adoption to be feasible.
