If you have been wondering whether it is 'right' (i.e. appropriate) to analyze pop music the way we've been doing, you may like to take a look at a recent PhD dissertation by Christopher Doll, "Listening to Rock Harmony" (Columbia University, 2007), available at http://www.columbia.edu/~ccd2005/research.html. Here is a rock music composer analyzing rock music the classical way! Do note, however, that his analytical system and symbols are not entirely the same as what we've been using in our class.
