PRPR4 (Prolongational Importance)
Let ek be the prolongationally most important event in
a region (ei-ej). Prefer a prolongational reduction in
which ek is an elaboration of the prolongationally
more important of the endpoints.
PRPR 5 (Parallelism)
Prefer a prolongational reduction in which parallel
passages receive parallel analyses.
PRPR 6 (Normative Prolongational Structure)
A cadenced group preferably contains four (five)
elements in its prolongational structure:
a. a prolongational beginning,
b. a prolongational ending consisting of one
element of the cadence,
(c. a right-branching prolongation as the most
important direct elaboration of the prolongational
beginning,)
d. a right-branching progression as the (next)
most important direct elaboration of the prolon-
gational beginning.
e. a left-branching "subdominant" progression as
the most important elaboration of the first
element of the cadence. |
