Writing compound and complex sentences is rarely used by my students in non-major English classes. When some students do try to use compound or complex sentences they often make errors. However, the ability of writing compound and complex sentences is one of the important writing skills to help students get high scores for fulfilling their subject at Cantho University and for later use in the working environment or further higher education in Vietnam or abroad. An idea which occurred to me was why not use something enjoyable such as pop songs to help the students to remember compound and complex sentences and then use them in their writing. Therefore, I decide to plan and implement a ten week action research project to find out the effect of songs on my students’ use of writing compound and complex sentences. Some songs with compound and complex sentences were to be applied in the class in listening activities, recognizing and analyzing them and singing performance. Then, the students will do some writing tasks with the hope of using them as many as possible.
