A Treatise on Simple Counterpoint in Forty Lessons

by Friedrich J. Lehmann

LESSON VIII

COMBINING THE FOURTH SPECIES WITH THE OTHERS

All previous rules for combining species still apply.

In combining the fourth species with other than the first, the following intervals may be used on the first half of the measure, in addition to those mentioned in Lesson VI: When the counterpoint is below, the fourth, fifth and seventh in suspension, and the ninth in retardation; and when above, the fifth in suspension, and the seventh in retardation; but in every such case the part having other than the fourth species must skip to some other chord-tone before resolving the suspension. [[Fig. 73.]]

Fig. 73.

The leading-tone may be doubled as in [Fig. 74.] Here the leading-tone that is prepared skips to some other chord-tone, while the new leading-tone remains stationary.

Fig. 74.

The minor or diminished seventh, major or minor ninth, may be used as preparation of a suspension in either part, provided it is approached by a skip in an upward direction, and is consonant with the other part, or is one of the permitted dissonances. [[Fig. 75.]]

The fourth species may be combined with the second or third species, and two or three notes syncopated may be written in one part with six in the other. [[Fig. 76.]]
