Efficiency Through Change Of Pitch

    Speech is simply a modified form of singing: the principal     difference being in the fact that in singing the vowel sounds     are prolonged and the intervals are short, whereas in speech the     words are uttered in what may be called "staccato" tones, the     vowels not being specially prolonged and the intervals between     the words being more distinct. The fact that in singing we have     a larger range of tones does not properly distinguish it from     ordinary speech. In speech we have likewise a variation of     tones, and even in ordinary conversation there is a difference     of from three to six semi-tones, as I have found in my     investigations, and in some persons the range is as high as one     octave.

    --WILLIAM SCHEPPEGRELL, _Popular Science Monthly_.

By pitch, as everyone knows, we mean the relative position of a vocal tone--as, high, medium, low, or any variation between. In public speech we apply it not only to a single utterance, as an exclamation or a monosyllable (_Oh!_ or _the_) but to any group of syllables, words, and even sentences that may be spoken in a single tone. This distinction it is important to keep in mind, for the efficient speaker not only changes the pitch of successive syllables (see Chapter VII, "Efficiency through Inflection"), but gives a different pitch to different parts, or word-groups, of successive sentences. It is this phase of the subject which we are considering in this chapter.

_Every Change in the Thought Demands a Change in the Voice-Pitch_

Whether the speaker follows the rule consciously, unconsciously, or subconsciously, this is the logical basis upon which all good voice variation is made, yet this law is violated more often than any other by _public_ speakers. A criminal may disregard a law of the state without detection and punishment, but the speaker who violates this regulation suffers its penalty at once in his loss of effectiveness, while his innocent hearers must endure the monotony--for monotony is not only a sin of the perpetrator, as we have shown, but a plague on the victims as well.

Change of pitch is a stumbling block for almost all beginners, and for many experienced speakers also. This is especially true when the words of the speech have been memorized.

If you wish to hear how pitch-monotony sounds, strike the same note on the piano over and over again. You have in your speaking voice a range of pitch from high to low, with a great many shades between the extremes. With all these notes available there is no excuse for offending the ears and taste of your audience by continually using the one note. True, the reiteration of the same tone in music--as in pedal point on an organ composition--may be made the foundation of beauty, for the harmony weaving about that one basic tone produces a consistent, insistent quality not felt in pure variety of chord sequences. In like manner the intoning voice in a ritual may--though it rarely does--possess a solemn beauty. But the public speaker should shun the monotone as he would a pestilence.
