My kids and I are loving Robert Greenberg's course, "How to Listen to and Understand Great Music." He's very funny and engaging, and weaves in lots of historical/social/cultural context. Today, for example, in "Intro to the Baroque Era," we got not only Bach, Handel, et al., but also Galileo, Kepler, Newton, Louis IV and the architecture of Versailles, and other illustrations of contemporary thought and artistic expression. Two thumbs up!
