Institutio Oratoria

I must warn my readers not to fall into the error of supposing that evenness and variety are incompatible with one another, since the fault opposed to evenness is unevenness, while the opposite of variety is that which the Greeks term μονοείδεια, or uniformity of aspect. The art of producing variety not merely charms and refreshes the ear, but, by the very fact that it involves a change of effort, revives the speaker's flagging energies. It is like the relief caused by changes in position, such as are involved by standing, walking, sitting and lying, none of which can be endured for a long time together.

But the most important point (which I shall proceed to discuss a little later) is the necessity of adapting the voice to suit the nature of the various subjects on which we are speaking and the moods that they demand: otherwise our voice will be at variance with our language. We must, therefore, avoid that which the Greeks call monotony, that is to say, the unvarying exertion both of lungs and voice. By this I do not simply mean that we must avoid saying everything in a loud tone, a fault which amounts to madness, or in a colloquial tone, which creates an impression of lifelessness, or in a subdued murmur, which is utterly destructive of all vigour.

What I mean is this: within the limits of one passage and the compass of one emotion we may vary our tone to a certain, though not a very great extent, according as the dignity of the language, the nature of the thought, the conclusion and opening of our sentences or transitions from one point to another, may demand.

Let us take as an example the opening of Cicero's magnificent speech in defence of Milo. Is it not clear that the orator has to change his tone almost at every stop? it is the same face, but the expression is changed. Etsi vereor, iudices, ne turpe sit,
