I’m not talking about marketing here, but the pitch that you use in your speech. Do you remember the music teacher using a special instrument (known as a pitch pipe)to ensure that everyone was on tune?
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, but gives a different pitch to different parts, or word-groups, of successive sentences.
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. 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.
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.
