Fourth Species in Three Voices
Explanation of suspensions in three voices is simplified if we have a name for each of the three voices involved. In two-voice fourth species we simply referred to the “syncopated voice” and to the C.F. But in three parts it is important, when dealing with dissonant suspensions, to be clear about the function of each of the three voices. We shall refer to the voice with the syncope-the suspension itself-as the suspension voice. The voice against which the suspension is dissonant is called the accompanying voice. The remaining one is the third voice.
