 +====== On Double Counterpoint ======
 +===== First Section: Double Counterpoint in Two Parts =====
 +==== Inversion at the Twelfth ====
  
 +These are the two rows of figures which should be compared together for obtaining the inversions of double counterpoint at the //twelfth//:
 +
 +^ Counterpoint  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |  8  |  9  |  10  |  11  |  12  |
 +^ Inversion  |  12  |  11  |  10  |  9  |  8  |  7  |  6  |  5  |  4  |  3  |  2  |  1  |
 +
 +It will be seen that the //unison// or //octave// changes, in counterpoint of this kind, into a //twelfth//, the //second// into an //eleventh//, //etc//.
 +
 +The //sixth//, which by inversion becomes a //seventh//, should be prepared either in the upper part, or the lower; and the bass should then descend one note or degree.

 +This counterpoint is one of the most used, and one of the most fertile in resources.
