This account of the intonation of English is part of ongoing research at the University of Birmingham, England. It attempts to take account of how intonation contributes to the communicative value of an act of speech. An introductory chapter provides a short discussion of some crucial terms: pitch, loudness, stress, rhythm, and tone unit. The seven chapters which follow discuss these aspects of intonation: (1) tone, (2) key, (3) the tone unit, (4) social meanings connected with tone, (5) key and termination, (6) intonation and discourse structure, and (7) reading intonation. An eighth chapter compares this description of the intonation of English with two other systems, one by O'Connor and Arnold, and the other by Halliday. The final chapter on intonation and language teaching considers critically the view of intonation that existing teaching materials present; it also makes some suggestions as to the kind of syllabus that might be derived from the model, and possible exercise types. Chapters 1-6 conclude with exercises on the intonation principles described in the chapter. (AMH)
