Intonation is the aspect of phonology that stretches over more than one syllable or a word. It is the rising and falling of the voice when speaking, and doesn't sound flat, to express feelings and attitudes. It is important as word choice; expresses how to say the thing rather than what to say. It is impossible to understand the expressions and thoughts without intonation, and the incorrect use of it can result in misunderstanding, speakers losing interest or even taking offence.The research is applied on students of second year, English department, college of Education for Humanities, University of Mosul. They are fifty male and female students who lack the correct use of English intonation when they are asked to make a dialogue or diagnose the function of suggested sentences. The sample is divided into two groups, control and experimental. The control group is taught according to the traditional method by reading the words and sentences according to the tone they carry, while the experimental group is taught with the use of discourse strategies for, according to Lane (2010), intonation cannot be acquired in isolation, but through discourse students will feel the functions of intonation and be conscious aware for the suitable tones. A T-test is dependent to check students' progress in recognizing and producing speech with correct intonation. Lane's work has been the stimulus to show the role of intonation in listening and speaking.
