====== On Double Counterpoint ======
===== First Section: Double Counterpoint in Two Parts =====
==== Inversion at the Eleventh ====

Double counterpoint at the //eleventh// or //fourth//, is now to be discussed, the combinations of which will be analyzed by the usual method of two rows of figures:

^ Counterpoint  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |  8  |  9  |  10  |  11  |
^ Inversion  |  11  |  10  |  9  |  8  |  7  |  6  |  5  |  4  |  3  |  2  |  1  |

From this view, the //sixth// is -- in this counterpoint -- the principal interval, and it is by that one, we should commence or finish; it is by that one, that not only the discords must be prepared and resolved, but also the concords, which are changed into discords by inversion.

The interval of the //eleventh// forms the limit of this counterpoint. A developed example is hereby given of a counterpoint of this kind:

{{ :cherubini_counterpoint_and_fugue:ex171a.mp3 | :cherubini_counterpoint_and_fugue:ex171a.ogg |}}

> 1st inversion

> 2nd inversion: Transpose the theme a fourth above, and the counterpoint an octave below

{{ :cherubini_counterpoint_and_fugue:ex172a.mp3 | :cherubini_counterpoint_and_fugue:ex172a.ogg |}}

> 3rd inversion: Transpose the theme a fifth below, while the counterpoint remains in its original place

{{ :cherubini_counterpoint_and_fugue:ex172b.mp3 | :cherubini_counterpoint_and_fugue:ex172b.ogg |}}

> 4th inversion: Transpose the theme a //fourth// above, and the counterpoint a //fifth// below

{{ :cherubini_counterpoint_and_fugue:ex172c-1.png?650 |}}

{{ :cherubini_counterpoint_and_fugue:ex172c.mp3 | :cherubini_counterpoint_and_fugue:ex172c.ogg |}}

> 5th inversion: Transpose the theme a //fourth// above, or a //fifth// below, and the counterpoint a //fourth// above or a //fifth// below

{{ :cherubini_counterpoint_and_fugue:ex172d-1.png?650 |}}

{{ :cherubini_counterpoint_and_fugue:ex172d.mp3 | :cherubini_counterpoint_and_fugue:ex172d.ogg |}}

Double counterpoint in the //eleventh//, is of all double counterpoints little used, that which may be employed with the fewest objections and difficulties.
