3 Dislocation Of Thematic Members
By this is meant, any exchange or
alteration of the regular and expected arrangement of members. This
can refer, naturally, only to what occurs after the Exposition,--that
is, during the Recapitulation; for it is the Exposition which
determines the plan, and regular order, of the thematic members. For
example, Mozart, pianoforte sonata. No. 13, first movement:--
Principal Theme, with Transition (measures 1-27).
Subordinate Theme (28-41).
Codetta I (42-53).
Codetta II (54-58). In the Recapitulation, the arrangement is thus:--
Principal Theme, Codetta I, Subordinate Theme, Codetta II; that is,
the first codetta appears before, instead of after, the Subordinate
theme.
