Avoid consecutive major thirds in major keys. In minor keys they are good.
[Fig. 14.]

[Illustration: Fig. 14.]

Use adjacent voices in writing, and do not exceed the vocal compass of a
voice.

Modulation may be resorted to within the exercises, but only to nearly
related keys; for example, in C, to G, F, a, e, or d.

At the close parts should proceed stepwise to the unison, or octave. [Fig.
15_a_.]

[Illustration: Fig. 15.]

A close as in Fig. 15_b_ may be used occasionally. In this case the
leading-tone is better in the higher part.
