252 Kilometers through Eastern Thailand: A Suite for Acoustic Guitar Quartet

Abstract

This creative research presents the conceptual framework and compositional process of “252 Kilometers through Eastern Thailand: A Suite for Acoustic Guitar Quartet”, aiming to generate new knowledge in contemporary music and to disseminate the work through live performance. The composition draws inspiration from the 252-kilometer highway linking five provinces in Eastern Thailand—Trat, Chanthaburi, Rayong, Chonburi, and Chachoengsao. This route provides the structural foundation for melodic and harmonic development, organized into four movements (A–D), each portraying the atmosphere, motion, and cultural identity of its respective region. 

The first movement (Trat–Chanthaburi) blends coastal folk melodies with flowing arpeggios and bright pentatonic tones, evoking the gentle rhythm of the sea. The second movement (Chanthaburi–Rayong) merges folk dance motifs with industrial rhythmic patterns, representing the coexistence of tradition and modernity. The third movement (Rayong–Chonburi) captures the joyful energy of coastal life through lively tempos and layered textures, reflecting the vibrancy of seaside festivals. The final movement (Chonburi–Chachoengsao) transitions toward inner tranquility, using sustained harmonics and soft pentatonic lines inspired by the serene flow of the Bang Pakong River.

Performed by an acoustic guitar quartet, the piece employs diverse techniques such as fingerstyle, percussive tapping, and textural layering to express emotional depth and depict the evolving landscape along the route. Ultimately, this composition offers a contemporary interpretation that unites sound, geography, and culture, symbolizing the spirit of travel through Thailand’s Eastern region.
