ABSTRACT
The full role played by Rhythm in the economy of nature is wrapt in mystery. Rhythm plays a large part in preventing fatigue is well known to anyone who has walked to the accompaniment of a band, but the idea that in mechanical work the rhythm of the machine must be fixed to suit that of the operator is new. Research on the physiological rhythmic changes in the body during the day has resulted in the discovery of the best relative times of work and rest, and the relation between output and fatigue. Rhythm is certainly a fundamental factor in human development. Children of a few months will beat time to a tune with marked rhythm, and the sense of rhythm is apparently at its height, and if not cultivated, may be lost. Spontaneous rhythm is present in the child’s free play, the spontaneous dancing movements which children give way to under all forms of pleasant emotion.
