MoLam is a cultural performance art in northeast Thailand. MoLam is a profession that requires the high art of singing and relies on literary aesthetics and elaborate melodies to attract listeners. The objectives of this study were to: 1) research and collect information about Isan MoLam's performing arts, 2) explore the current conditions and problems affecting MoLam's performing arts literacy inheritance, and 3) investigate the process of transmission literacy to inherit MoLam's performing arts literacy. Descriptive analysis was used to examine and data from documents and fieldwork. The results of this study are as follows: (1) According to MoLam research, when the colonial country invaded this region, the Thai-Lao ethnic culture in northeastern Thailand and Lao PDR was split. On the Thai side, individuals flocked to the center area to meet with Siam. MoLam in the Northeast has steadily developed since then, and it may be classified into four types: (i) non-dramatic MoLam, (ii) dramatic MoLam, (iii) ritual MoLam, and (iv) miscellaneous MoLam. (2) As Thai society enters the internet era, there are numerous popular entertainment mediums, leading people's morals to shift and lowering people's interest in viewing MoLam performances and roles. The goal is to find a way to pass down this performance art to future generations. (3) Literacy transmission: After synthesizing the material to be taught, the students are separated into two groups: (i) MoLam singing has been practiced by a group of elementary and high school students; (ii) MoLam singing, and music have been practiced by a group of students at higher education institutions. Under the established parameters, both groups have extra talents. In conclusion, this study may be utilized as a model for conveying local wisdom information.
