Part Ii
The departure (more or less emphatic) from this leading
melodic statement. It is, for a time, probably an evident continuation
and development of the melodic theme embodied in the First Part; but it
does not end there; it exhibits a retrospective bent, and--when
thoroughly legitimate--its last few measures prepare for, and lead
into, the melodic member with which the piece began. Its form is
optional; but, as a rule, decisive cadence-impressions are avoided,
unless it be the composer's intention to close it with a perfect
cadence (upon any other than the principal tonic), and accomplish the
return to the beginning by means of a separate returning passage,
called the Re-transition.
