Dave Rawlings completed this course, spending 7 hours a week on it and found the course difficulty to be medium.
I'm the most unmusical person in the world (so my wife says), and had no knowledge of classical music before starting the course. I found some of it challenging, especially the sections that concentrated on the technical aspects of the music. Nevertheless I felt I gained a lot, now have a little knowledge, and enjoyed the course. The professor's approach is very engaging and covers the historical development very well.
