The course materials, videos and lectures were great. The quizzes were a bit odd - strange wording and sometimes out of order with the teaching units.
The content of the course is absolute gold. The course provides some answers (or at least partial answers) to very intriguing questions in music: Why these notes and not others? Why is a minor scale "sad" ? and other related questions. The only real issue is the that the quiz questions are just garbage, so be prepared to be frustrated that after learning some new material and having some real "aha!" moments you will fail the quiz because the questions don't really seem to reflect the important points.
