We will follow the following steps:

  1. We return to first species and fourth species in three parts
  2. We add two parts in mixed values to a CF
  3. We leave the CF behind and write all three parts in mixed values
  4. We make imitative openings in three parts

Hard rules

  • Only vertical consonances are allowed.
  • A fourth may occur between the upper two parts, as long as the lowest voice has a third or fifth below the middle voice
  • Augmented fourth and diminished fifth may be used as consonances between the upper two voices as part of a "diminished 6/3 chord"
  • At least two out of three voices must begin and end on a perfect consonance, but the third voice may make a third above the lowest note
  • In fourth species, the 9-8 (or 2-1) suspension and the 4-5 suspension may be used as long as there is some imperfect consonance at the moment of resolution.
