The subject of Rhythm in what are called the Fine Arts is so vague, and has received so little attention, that some courage, or perhaps foolhardiness, is needed to attack it. And in offering the following fragmentary ideas that have been stumbled on in my own limited practice, I want them to be accepted only for what they are worth, as I do not know of any proper authority for them. But they may serve as a stimulus, and offer some lines on which the student can pursue the subject for himself.
