In this species, four notes are written in the counterpoint to each note of the cantus firmus. The counterpoint may begin on the first, second, or fourth quarter. The second quarter is, however, the most usual. [[Fig. 42.]]

The exercises should begin and end with tonic harmony.

When the counterpoint begins on the first quarter it must form a perfect consonance with the cantus firmus. When on the second or fourth quarter, any consonance may be used.

All previous rules are to be regarded, unless exceptions are made.

At least one of the first three quarter-notes of a measure should be left degreewise. [[Fig. 43.]]
