The first education a child needs is to harmonize its thought, speech, and action. All things external have their reaction in one's inner life, and the inner has its reaction on the exterior. Therefore some knowledge of tone and rhythm is essential at the beginning of the child's education. A child should be taught the elements of music with regard to the pitch in which it should get in touch with its friends, with strangers, with its parents, while playing or at table; in every varying condition it should feel that the pitch is different. The child should be taught how to make its choice of words when speaking to different people, to strangers, to its friends, to its parents, to the servants in the house; making the voice softer or louder must be done with understanding.
