This week, Michelle, Scott, and Karl listen to the Prelude Op. 28, No. 4 by Frédéric Chopin in E minor. We are listening to the Nino Gvetadze version which you can access here. As Michelle points out, "This is the clearest example of what happens when you put notes together and you just change them little by little." In other words? Harmony.  Harmony has the capacity to elevate a piece of music from common and predictable to challenging and sophisticated. Whether or not you believe harmony to be its own form of rhetoric, Karl reminds us, "Being able to know what someone is doing makes your peaks higher.”  Tune in to hear more music and ideas, brought to you by Online Great Books.
