Dissonantes sunt, in quibus vox prima, cum est elata in altitudinem, offensa superioribus solidis corporibus repulsaque residens in imo opprimit insequentis vocis elationem; circumsonantes autem, in quibus circumvagando coacta exsolvens in medio sine extremis casibus sonans ibi extinguatur incerta verborum significatione; resonantes vero, in quibus, cum in solido tactu percussa resiliant, imagines exprimendo novissimos casus duplices faciant auditu; item consonantes sunt, in quibus ab imis auxiliata cum incremento scandens egrediatur ad aures disserta verborum claritate.
The dissonant places are those in which the voice, when first it rises upwards, meets solid bodies above. It is driven back, and settling down, overwhelms the following utterance as it rises. The circumsonant are those in which the voice moves round, is collected and dissipated in the centre. The terminations of the words are lost and the voice is swallowed up in a confused utterance. The resonant are those in which the words, striking against a solid body, give rise to echoes and make the termination of the words double to the ear. The consonant also are those in which the voice reinforced from the ground rises with greater fulness, and reaches the ear with clear and eloquent accents.
