Thai Classical Music ‘Tub Kheak Sai (Oh Phra Phai)’ Song Played by Acoustic Guitar Quartet

Abstract

This creative research project aimed to (1) develop the Thai classical composition Tub Khaek Sai (Oh Phra Phai) for acoustic guitar quartet and (2) disseminate the resulting arrangement through musical notation and audio recording. The study employed a creative research methodology that integrated musical analysis, reharmonization, arrangement, score preparation, and performance production. The original composition served as the primary source material, while principles of Western music theory, jazz harmony, and guitar arranging techniques were applied to create a contemporary adaptation suitable for acoustic guitar ensemble performance.

The arrangement was developed as a four-part texture consisting of melody, harmonic support, chordal accompaniment, and bass functions. To enhance the musical character of the work, the researcher employed various compositional and arranging techniques, including broken chords, staccato articulation, motivic development, intervallic writing, interval alteration, drop-2 voicings, rhythmic augmentation, and rhythmic diminution. The original key was transposed from B-flat major to E major to better accommodate the technical and idiomatic characteristics of the guitar.

The results of the study demonstrate that Thai classical music can be effectively adapted for contemporary guitar ensemble performance while preserving its essential melodic identity. The project produced a complete performance score and professional audio recording, providing valuable educational, performance, and research resources for musicians, students, and scholars interested in Thai music adaptation and cross-cultural musical development. The study also contributes to the preservation and dissemination of Thai musical heritage through contemporary creative practice and digital media.
