A coincidence, I watched a doco on TV last night covering the relationship between music and humans and one of the conclusions was that life itself is based on rhythm so we all have this built in ability to connect with even the most basic of rhythm/music even a new born child, it is present even in our languages which confirms a hobby horse of mine which is that a composers music reflects his used language and that we use (for want of a better term) a major key to express joy and happiness and a minor key to express sadness, I recorded the program so will watch it again. A fascinating subject.
