When we listen to the music of certain composers, we can immediately say "I recognize that sound!" But why? What techniques is that composer using in their music to convey that instantly recognizable sound to us? In this episode, I dive into the Baroque Era, and one of its icons, Johann Sebastian Bach. I look at some of his music - primarily keyboard music, but also a feature of the Brandenburg Concertos - and try to demystify the sound that has become so associated with him.
