Chapter 3

The note under the hold may be continued the extra measure, or the part may rest and then reënter. All that is required is that it begin after the lapse of one measure, i.e., when the line ends on the accent the next line begins on the weak beat of the measure following, and if it ends on the weak beat then on the accent of the next measure.

The interval at any hold except the last of a choral may be either a perfect (_a_) or imperfect consonance (_b_). [Fig. 156.]

Modulation often occurs at the holds. If so, make it clear.

In this and in succeeding lessons set the cantus firmus in any part, and transpose if necessary.

EXERCISES

To cantus firmus _b_ write two counterpoints above and two below.

To cantus firmus _a_ write one above and one below, with both parts resting at the hold. Also do the same _with the counterpoint continuing at the hold_. [Fig. 155_a, b._]

LESSON XXXIV

FREE HARMONIZATION IN THREE-PART COUNTERPOINT

When writing in three or more parts, it is well to let a part rest occasionally, and, when it reënters, have it imitate one of the other parts. [Fig. 158.]

To cantus firmus _a_ write two counterpoints above and two below in two-part counterpoint.

Write two original eight-measure phrases in two-part counterpoint.

To cantus firmus _b_ write one example in three-part counterpoint with continuous movement at the hold. [Fig. 159.]
