Each measure should usually contain a complete chord. If not complete on
the first beat, bring the missing interval in on the second. [Fig. 98.]

[Illustration: Fig. 98.]

The cadences in Fig. 99 are good, and will suggest others. The use of the
fourth species is permitted as at _a_. A note may be repeated in the final
cadence in all species as at _b_.

[Illustration: Fig. 99.]


EXERCISES

To cantus firmus _a_ write the first species in all parts, as previously
directed.

To cantus firmus _b_ write second species in one part. Write three times,
changing cantus firmus and counterpoint about so that they will appear in
each part in turn.
