I have been teaching AP Music Theory now for 12 years. In that time my philosophy has dramatically shifted from trying to teach all of the material to trying to create meaningful experiences with all of the material so that the students want to pursue it more in college. Here are some tunes my class has “group composed” regarding part writing rules. The third tune was the week we introduced NCT’s so they felt compelled to include their new found tools. Now, if we start our homework in class and someone asks a question or has forgotten one of these rules, I just simply start humming it or playing it on the piano. Both the pdf and the mp3 file is available for download. Enjoy.
