In the nature, there are three patterns of fluctuation classified by frequency spectrum. They are white fluctuation, 1/f (pink) fluctuation and brown fluctuation. Between the three, it has been reported that pleasant state of mind is supplied by any 1/f fluctuation. In order to create a natural music automatically, we applied this 1/f fluctuation to musical composition and arrangement, which is one of the brain works. Same experiments have been reported, but in this system we used new algorithm for generating 1/f fluctuation we developed.
