How was the tritone used? |
 | | However, at least by the epoch of Perotin and his successors, while the tritone was typically classified in the 13th century as a "perfect discord" (along with m2 and M7), it nevertheless occurs, as do these intervals, quite frequently and prominently in practice. |
 | | Indeed, there are many 13th-century cadences where the tritone serves basically as a "counterfeit fourth or fifth," and Boen suggests that similar progressions may sometimes have occurred in the 14th century as well. |
 | | In a medieval context, where fifths and fourths are the most complex stable intervals, the tritone is unique among the usual intervals in neither being itself stable, nor in being to resolve to any stable interval by conjunct contrary motion: compare 2-4, 3-1 or 3-5, 6-8 or 6-4, and 7-5. |
