Chapter 9 addresses intonation, the tonal melody that contributes to the interface between phonology, on the one hand, and syntax and semantics, on the other. It is shown how the φ-phrase and the ι-phrase are identified not only by their phrasing and their metrical structure but also by their tonal structure. These high-level constituents are the domains of assignment of intonational tones associated with stressed syllables and edges of φ-phrases and ι-phrases (i.e., pitch accents, phrasal tones and boundary tones). These tones form melodic tunes that deliver not only grammatical information but also pragmatic and so-called “paralinguistic” meanings.
