As a farewell illustration, to sum up the meaning of the quality and expression of tone, let me return to sound tones. Have you ever thought of quality and expression in the case of your own voice? I do not mean the singing voice. Many of us do not possess this kind of voice; but we all have a speaking and reading voice. What are the quality and expression of yours? I am thinking now of the way you use it; of the quality and expression of the sounds you utter.
