EXERCISES
Write six eight-measure phrases, using the fifth species in all the parts. Let the parts begin one after the other in imitation. [[Fig. 151.]]
LESSON XXXIII
FLORID MELODIES AS CANTI FIRMI
FREE HARMONIZATION IN TWO-PART COUNTERPOINT
| Fig. 152. |
Thus far, all notes in the measure foreign to the harmony on the first beat were treated as dissonances. Now, the cantus firmus may be harmonized at pleasure, the only restriction being that any tone foreign to the chord with which it enters must be treated as a dissonance. [[Fig. 152.]]
It is not necessary that each part be strictly florid, but that the effect of the parts as a whole should be so. This applies from this point to the end of these lessons.
The suspension may now be a quarter-note, or its rhythmic equivalent. It then comes on the first (a) or third (b) quarter of the measure, and the resolution on the quarter following. The preparation should be as long as, or longer than, the suspension. [[Fig. 153.]]

The eighth-note as in [Fig. 154a] is good. It should be used only on the second half of a weak beat, and be preceded by a dotted quarter-note. Sixteenth-notes may be used in place of the eighth-note, but should be approached and left step-wise. [[Fig. 154b].]
