What follows is a guest post by Jennifer Judkins. Jennifer is an Adjunct Professor at the UCLA Herb Alpert School of Music, where she teaches music bibliography for performers and guides graduate research. She spent many years standing in the back of orchestras counting rests, and her musings between timpani rolls have nursed many years of interest and writing in aesthetics, especially in regard to musical performance.
