 +====== On Double Counterpoint ======
 +===== Second Section =====
 +==== Triple and Quadruple Counterpoint at the Tenth ====
  
 +By observing the rules laid down in the first section on the subject of //double// counterpoint at the tenth, as well as the laws which ordain the necessity of employing //contrary// movement and //oblique// movement, //triple// and //quadruple// counterpoint at the //tenth// will be obtained.

 +{{ :cherubini_counterpoint_and_fugue:ex182.mp3 | :cherubini_counterpoint_and_fugue:ex182.ogg |}}
 +
 +In order to convert this //double// counterpoint into //triple// counterpoint, nothing is required but to add to these two parts the inversion of the upper part a //tenth// below, or that of the lower part a //tenth// above.

 +{{ :cherubini_counterpoint_and_fugue:ex183b.mp3 | :cherubini_counterpoint_and_fugue:ex183b.ogg |}}
 +
 +In order to obtain //quadruple// counterpoint, the following example of a //double// counterpoint at the //tenth// is first proposed:
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184a-1.png?650 |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184a.mp3 | :cherubini_counterpoint_and_fugue:ex184a.ogg |}}
 +
 +Of this //double// counterpoint, a //triple// counterpoint is formed, by adding a third part at the distance of a //tenth// or a //third// from one or other of the two existing parts; and by inverting, alternately, each of these parts in the manner worked out in the example of a //quadruple// counterpoint at the //octave//.
 +

 +
 +{{ :cherubini_counterpoint_and_fugue:ex184b.mp3 | :cherubini_counterpoint_and_fugue:ex184b.ogg |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184c-1.png?800 |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184c.mp3 | :cherubini_counterpoint_and_fugue:ex184c.ogg |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184d-1.png?800 |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184d.mp3 | :cherubini_counterpoint_and_fugue:ex184d.ogg |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184e-1.png?800 |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184e.mp3 | :cherubini_counterpoint_and_fugue:ex184e.ogg |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184f-1.png?800 |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184f.mp3 | :cherubini_counterpoint_and_fugue:ex184f.ogg |}}
 +
 +By adding to this same double counterpoint the two parts in thirds, in the following manner, a quadruple counterpoint at the tenth will be obtained:
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184g-1.png?800 |}}
 +
 +{{ :cherubini_counterpoint_and_fugue:ex184g.mp3 | :cherubini_counterpoint_and_fugue:ex184g.ogg |}}
 +
 +This counterpoint -- at least, as it is combined in the above example -- gives but few inversion exempt from reproach.
