Musithetics

I popped into Haze, a blues bar, today. I had an office mate coming over along with his guitar teacher. Lets refer to the teacher as G. Now G happens to be a blues man. He happens to be so a blues man that he starts de-constructing every song that's being played. 'Okay a fifth bar, three -- 12 bar'. This struck me as extremely sad. Imagine listening to music as a mathematical equation! What is the point of listening to it at all then?
