This lecture shows how the character and quality of music reflects the harmony of its society, especially the prospects for love and happy marriage. Since the 1920s and early to mid 1930s, American music has deteriorated in step with the decay of the American Empire. Computers are also and everywhere to blame because the computer keyboard has replaced the piano keyboard in our lives, and computers cannot create music.If music is to get back on track —or even survive! —governments will have to subsidize computerless music schools, and China will have to present the world with a much better social model than America did.
