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.
