# The Phonology of Tone and Intonation (2)
**Opening (not a real abstract):** The Phonology of Tone and Intonation Tone and Intonation are two types of pitch variation, which are used by speakers of many languages in order to give shape to utterances. More specifically, tone encodes morphemes, and intonation gives utterances a further discoursal meaning that is independent of the meanings of the words themselves. In this comprehensive survey, Carlos Gussenhoven provides an up-to-date overview of research into tone and intonation, discussing why speakers vary their pitch, what pitch variations mean, and how they are integrated into our grammars. He also explains why intonation in part appears to be universally understood, while at other times it is language-specific and can lead to misunderstandings. The first eight chapters concern general topics: phonetic aspects of pitch modulation; typological notions (stress, accent, tone, and intonation); the distinction
