The book is describing how the brain works in a musical way. How people see the world through musical eyes, and through musical perception. Musical chords are in the basic of every brain expression, in the past and in the present: including scientific theories, paintings, movies, plays, books, speeches, conversations, and so on. People see space and time in terms of music: they see anything in terms of music. People being aware to themselves as musical creatures, can improve their way of life in many aspects, because through music, reality becomes very accurate, clear, transparent, aware.
