This document discusses intonation patterns in English: falling intonation, rising intonation, rise-fall intonation, and fall-rise intonation. Falling intonation, where the voice falls at the end of a sentence, is used for statements, commands, WH-questions, and exclamations. Rising intonation, where the voice rises at the end, is used for yes/no questions and question tags that require an answer. Rise-fall intonation has a rising then falling pattern and is used for choices, lists, unfinished thoughts, and conditional sentences. Fall-rise intonation is used to show hesitation or reluctance in responses.
