Countermovement (counterpoint)
In musical theory of counterpoint , the countermovement (lat. Motus contrarius) is the movement ratio of two voices, one of which rises and the other falls. Countermovement is seen as a sure means of avoiding forbidden parallels ; however, the counter-movement from a perfect consonance to an octave- identical interval (fifth-duodecime, octave-unison etc.), the so-called antiparallel , is also forbidden in low-voiced movements.
