or a whole speech, in about the same force, rate, and general pitch, is
one that may be considered from another point of view. One fault in the
delivery of sentences--perhaps the most frequent one--is that of
running them all off in about the same modulation. By modulation we
mean the wavelike rise and fall of the voice that always occurs in some
degree in speech,--sometimes called melody--and the change of key, or
general pitch, in passing from one sentence, or part of a speech, to
another. Frequently, novices in speaking and in reading, will swing the
voice upward in the first part of every sentence, give it perhaps
another rise or two as the sentence proceeds, and swing it down, always
in precisely the same way, at the end. The effect of this regular
rising at the beginning, and this giving of a similar concluding
cadence at the end, is to make it appear that each sentence stands
quite independent of the others, that each is a detached statement; and
when, besides, each sentence is given with about the same force and
rate of speed, they all seem to be of about equal importance, all
principal or none principal, but as much alike as Rosalind's halfpence.
Sentences that have a close sequence as to thought should be so
rendered that one seems to flow out from the other, without the regular
marked rise at the beginning or the concluding cadence at the end.
Sentences, and parts of sentences, which are of less importance than
others with which they are associated, should be made less prominent in
delivery. Often students are helped by the suggestion that a sentence,
or a part of a sentence, or a group of sentences, it may be, be dropped
into an undertone, or said as an aside, or rapidly passed over, or in
some way put in the background--said, so to speak, parenthetically.
Other portions of the speech, or the sentence, the important ones,
should, on the same principle, be made to stand out with marked effect.
