Lesson 13 - Simple Counterpoint in three parts - Third Species in two parts

[MaestroX]

THIRD SPECIES IN TWO OR MORE PARTS

Fig.110.


Previous suggestions when two or more parts have other than first species, apply here.

In using the ninth of a chord it is well to keep it at least a seventh distant from the third, as well as a ninth above the root, except in the case of the dominant ninth in minor keys, where it may be separated by only an augmented second ([b]). [Fig. 111.]

Fig.111.


In writing the third species in all parts, notes appearing simultaneously should be harmonically related. Treat all tones foreign to the chord on the first quarter as dissonances.

The cadences in Fig. 112 are good.
