LESSON XV

THIRD SPECIES IN TWO OR MORE PARTS


[Illustration: 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.]

[Illustration: 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.
