LESSON VI

FOURTH SPECIES


[Illustration: Fig. 62.]

This species is the same as the second, except that the last note of the
measure is tied to the first note of the next, forming a syncopation. As in
the second species, the first note of the counterpoint should form a
unison, octave or fifth, and when the counterpoint begins on the second
half it may also be an imperfect consonance.

When the counterpoint begins on the first half, the second half is treated
the same as the second half of succeeding measures, described in the next
paragraph.
