Library Worksheets: Resources for each of the four levels In the essay, "The Power of Music," the effects of music were categorized on four levels: the physical, the psychological, the symbolic, and the transformational. Use these worksheets to record citationsfor journal articles, essays, sections of books, web sites, and other scholarly resources that describe issues, studies, questions, et al. related to each level. The resource for the physical level that you will present for RWA #1 may be chosen from these; the others may serve as resources for the assignments throughout the rest of the semester, including your semester research report. Consider these worksheets as brainstorm tools for you to gather your ideas. The contents of these worksheets will be shared in general discussions of topics.
