Excellent advice from Stringreen. I would add what would likely be an important aspect of any good music appreciation class. Approach your exploration of this fantastic genre in a way that looks at and considers the chronology of the evolution of the music. Music from more recent periods or current are much more meaningful and more easily appreciated if there is, at least, some exposure to music from earlier periods. Enjoy!
