I like anything that leaves me with a feeling that I've learned a secret or some kind of inside information. This is a strong piece that did just that for me. It focuses on "single chord from an epic five hour opera" and outlines its influence on music to this day, complete with examples and interesting mash-ups. This is not simply a musical piece, it stands well on its own and the way it's produced will allow it to be included in many different formats, or between various segments. Although it only runs just over fifteen minutes, I didn't feel it left anything out - while still making me curious to hear more about Wagners music and more in this series.
