Music topics can be general, large topics like genres, artists, or movements. These general topics are better suited for lower-level music courses instead of junior or senior level courses. When you get into graduate classes or more specific courses, it is better to focus on narrowed topics. When you choose a topic for a music research paper, you should always be sure the topic is arguable and does not have an obvious answer. If you want to make the topic more interesting for your and your reader, you can always argue the side that no one would imagine to be arguable.
