| ===== First Section: Double Counterpoint in Two Parts ===== |
| ==== Inversion at the Fourteenth ==== |
| |
| It remains, finally, to speak of double counterpoint at the //fourteenth// or //seventh//. Here are two series of figures which give the inversions: |
| |
| ^ Counterpoint | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | |
| ^ Inversion | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | |
| |
| According to the above combinations, two //thirds// in succession must be avoided, particularly by similar movement; since, in transposition, they produce two //fifths//. Every concord, as well as the //octave// and the //sixth//, which become discords when inverted, should be prepared and resolved either by the //third//, or by the //fifth//. |

| |
| The range of the //fourteenth// serves as the limit of this counterpoint. |
