- the A section is repeated, then the B and A’ sections are repeated together
- PAC
- through harmonic-tonal and phrase-structural means: an emphasis on the home-key dominant, looser formal organization, weaker cadential closure
- (1) as a standing on the dominant; (2) as a continuation phrase ending with a HC
- (1) bring a return of the basic idea of the A section; (2) close with a home-key PAC
- (1) the HC ending the antecedent; (2) the return of the basic idea
- dominant prolongation is type of harmonic progression per se; standing on the dominant is a post-cadential formal function (supported by a dominant prolongation)
- to motivate a resolution to tonic harmony at the return of the basic idea
- that formal type, with its authentic cadential closure, is too tight-knit for a B section
- retransition
