Anna K. Howard, The Canadian Elocutionist
“ The upward is called the rising inflection, and the downward the falling inflection, and when these are combined it is known as the circumflex.The rising inflection is used in cases of doubt and uncertainty, or when the sense is incomplete or dependent on something following. The falling inflection is used when the sense is finished and completed, or is independent of anything that follows.Indirect questions usually require the falling inflection.Falling inflections give power and emphasis to words. Rising inflections give beauty and variety. ”
