LESSON XV

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 (). [[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.
