Ritual Music in Chao Huan Sam Pra Ong Ceremony

Abstract

This study examined the role of music in the Ritual of Worshipping the Spirit Shrine of the Three Lords (Chao Huan Sam Pra Ong) and analyzed its musical characteristics.

The research identified seven primary functions of ritual music: expressing belief; serving as a ceremonial ensemble; acting as a medium for communication with sacred beings; enhancing emotional and participatory engagement; representing local cultural identity; preserving traditions and culture; and functioning as a signaling system. The ritual was annually performed in the sixth lunar month, prior to the planting season.

The principal instruments used in the ceremony were the khaen (free reed mouth organ) and gong, both of which were considered essential. The khaen melodies consisted of thirteen traditional patterns, such as Lai Loe Ban Yao Yai, Lai Si Khot Ta Boon, and Lai Lam Phloen. The range of the khaen extended from low "La" (below Middle C, on the second ledger line below the staff) to high "La" (on the first ledger line above the staff). The melodies were performed using three tonal modes: the ionian mode, the dorian mode, and the mixolydian mode (a traditional pentatonic scale). The musical pieces were performed in simple duple meter, with the gong maintaining a steady rhythm throughout each measure, functioning similarly to a beat that provided temporal consistency.

The first set of khaen ritual patterns comprised eight rhythmic pulse groups, with the third group serving as the principal rhythmic pulse, characterized by the greatest descending motion. The second set contained twenty-five rhythmic pulse groups, with the fourth group functioning as the main rhythmic pulse, exhibiting the most stable  directional flow. It was observed that the khaen melodies featured a higher frequency of notes than the gong melodies, which maintained a consistent note density across every measure. The tonal colors of the music were integral to enhancing the spiritual and emotional dimensions of the ritual, ranging from solemn and sacred to festive and joyful atmospheres.
