The harmony of life can be learned in the same way as the harmony of music. The ear should be trained to distinguish both tone and word, the meaning concealed within, and to know from the verbal meaning and the tone of the voice whether it is a true word or a false note; to distinguish between sarcasm and sincerity, between words spoken in jest, and those spoken in earnest; to understand the difference between true admiration and flattery; to distinguish modesty from humility, a smile from a sneer, and arrogance from pride, either directly or indirectly expressed. By so doing the ear becomes gradually trained in the same way as in music, and a person knows exactly whether his own tone and word, as well as those of another, are false or true.
