This research aimed to investigate the effects of the two different types of warm-up exercises on learning singing ability for 5th-grade students. In a quasi-experimental research design, 70 5th-grade students from two intact classes were assigned into two groups. An experimental group was to apply an integrative warm-up exercise designed by Yu-Wen Pan (2002). By contrast, a control group did regular warm-up exercises by following the direction of 10th Music Book (Nan-I, 2001). Sixteenth class sessions were given to both groups within two months. Both groups were required to take a singing pre-test of previous learned songs, and a singing post-test of two vocalizations and selected songs. In addition, all 70 students were given a self-evaluation questionnaire during the post-test period, concerning their singing ability. The results of this research were founded as an integrative warm- up exercises could develop better singing skills for the students.
