Music of every kind appeals to someone. The best or the worst, somebody likes it. Have you not seen how children enjoy themselves with a little tin can and a stick? The rhythm comes within their capacity of enjoyment. Human nature is such, when you put it all together, it takes in everything, from the highest to the lowest. It has such a wide capacity that there is nothing left out. All has its place and all is assimilated by human nature. But at the same time there is action and reaction. It is not only the grade of evolution which makes man change his fancy to different colors and tones, but it is different colors and tones that help him also in his evolution, and they change the speed of one's evolution.
