Musical Offerings ⦁ 2025 ⦁ Volume 16 ⦁ Number 1 21 against note counterpoint throughout Missa Papae Marcelli. One such passage is the opening two and a half measures of the Gloria where all the voices move together in consonant intervals. (See Example 2). Example 2: Missa Papae Marcelli, Gloria, mm. 1–3 Second species counterpoint by Fux’s standards must occur in a duple meter context. It sets a whole note against two half notes. The downbeat interval must be consonant. On the second half note the interval can be dissonant if it is approached by step, or if approached by leap, it must be consonant.44 In Palestrina’s Mass, he does not strictly use whole notes set against half notes very often. However, there are instances where he will incorporate it in some but not all of the voices, such as measure forty-four of the Gloria where the cantus and bassus II have whole notes and the altus and bassus I have half notes. The tenor I and II have different rhythms from the other voices. (See Example 3). 44 Fux, 41.
