THE DEVELOPMENT OF THAI STYLE BRASS BAND EXERCISES ACCORDING TO THAI FOLK BRASS BAND KU – LARB SHOW BRASS BAND

Abstract

This quantitative research aimed to: 1) develop music exercise materials for brass bands based on the folk performance concepts of the Kularb Show brass band, and 2) determine the efficiency of these developed music exercise materials.The sample group consisted of 20 students majoring in Western Music (Vocational Certificate level, Years 1–3) at Angthong College of Dramatic Arts, Bunditpatanasilpa Institute, during the first semester of the 2023 academic year, selected through purposive sampling. The sample was divided into three instrument groups: woodwinds, brass, and percussion.The research methodology involved three steps 1. Reviewing relevant literature and research on music exercise creation based on folk brass band concepts and efficiency evaluations to define the content scope. 2. Evaluating content validity through expert review by three specialists to ensure the suitability of the exercises for instructional use. 3. Assessing the efficiency of the music exercises using basic statistical analysis.

The research findings revealed that 1. The quality of the exercise materials evaluated by the three experts yielded an average score of 4.49, indicating an appropriate level for instructional use. 2. The developed music exercise materials achieved an efficiency process/result ratio (E1/E2)of 81.19/97.96. The process efficiency (E1) reached 81.19% and the outcome efficiency (E2) reached 97.96%, both exceeding the standard 80/80 threshold. These findings suggest that the exercise materials can be applied as a practical guide for students, educational institutions, and individuals interested in local brass band culture to promote lifelong learning.
