 +====== On Double Counterpoint ======
 +===== Second Section =====
 +==== Triple and Quadruple Counterpoint at the Twelfth ====
  
 +In order to obtain //triple// and //​quadruple//​ counterpoint at the //​twelfth//,​ it will be necessary, after first combining it according to its appointed rules, to proceed in the same manner as already done, with regard to counterpoint at the //octave//; that is to say, by taking care to avoid discords that are not passing ones, and by scrupulously observing contrary or oblique movements. ​

 +
 +In order to form a //triple// counterpoint from a //double// one, there need only be added a third part, either a third below the upper part, or a third above (or below) the lower part.
