Abstract


This study aimed to evaluate the effectiveness of basic vocal training exercises for students at Yamaha Music School in Mahasarakham, Thailand, using a quantitative research approach. The research focused on collecting measurable numerical data and was divided into two main components: content validity assessment and effectiveness evaluation of the exercises using the E1 and E² efficiency measures. The statistical methods used for data analysis included Arithmetic Mean, Percentage, and Standard Deviation (SD). The findings indicate that the developed vocal training exercises consist of five core components: Breathing and Breath Control, Correct Pronunciation, Listening and Singing on Pitch, Voice Range Development, and Expressing Emotions through Singing. The content validity assessment yielded an Index of Item-Objective Congruence (IOC) of 0.95 and a Standard Deviation (SD) of 0.01, confirming that the exercises align well with academic standards and instructional objectives. The efficiency evaluation of the exercises (E1/E2) resulted in a score of 80.5/84.9, surpassing the standard benchmark of 80/80. These results demonstrate that the exercises effectively enhance students' fundamental vocal skills and can be successfully implemented to improve vocal training at Yamaha Music School, Mahasarakham, Thailand.
