It is natural for the heart and spirit to take pleasure and enjoyment in all things that show forth symmetry, harmony, and perfection. For instance: a beautiful house, a well-designed garden, a symmetrical line, a graceful motion, a well written book, pleasing garments -- in fact, all things that have in themselves grace or beauty are pleasing to the heart and spirit -- therefore, it is most certain that a true voice causes deep pleasure.
