Although it is well known that music can affect cognitive processes, little research has been conducted examining the influence of background music on students in information literacy classrooms. In 2010, librarians at Western Michigan University investigated the effect of background music on student engagement and retention of information literacy concepts. This article examines the theory and practical applications of background music to improve a classroom atmosphere and its impact on students' learning. Results from this qualitative and quantitative study indicate positive correlations between background music and student comfort, confidence, and retention. (Contains 6 tables and 1 note.)
