Tone and rhythm, the principal elements which constitute music, are the only principles of this creation, and may be traced in its beginnings, in its continuity, and in its end. People of lofty and of low ideals, of amiable or unamiable disposition, show the difference of pitch in them. Balance in man, in his thought, speech and deed, in time show rhythm in him. The winning personalities of the world show music in their voice and words. And even before he utters a word, a person shows stupidity in the movements of his body, for they are unrhythmic.
