This article is part of the research titled “The Development and Principle of “Ketduriyakom” Thai String Ensemble with Piano” aimed to present the development of the learning of Thai classical music through string ensemble bands in Thailand. Thai string ensemble with an addition represents the conceptual transcendence from the string band of the past, shows the adjustment between Thai and non-Thai music, reflects the ideas of contemporary music in its concept as well as performance and ensemble principles that differ and challenge the formulae of Thai classical music performance in the old days. Therefore, the development of Thai classical music bands in different periods reflects the adoption, exchange and values of external cultural currents that have driven the creative energy and stimulated the application of traditional culture to adjust to western influences.
Thai string ensemble with an addition reflects the transitions in the instruction of Thai classical music lessons. In the past, the instruction was mainly given at home or in a music school. Due to the oral tradition and one-on-one instruction custom of knowledge transfer, the instruction pattern of all types of Thai classical music was under this learning system. This was changed after Siamese musicians’ ways of life were influenced by the Industrial Revolution and western ways of recreation. New forms of ways of living and learning were adopted in large and various areas, not only in the metropolitan area. Moreover, the development of the printing press transformed the communication of knowledge into forms such as self-study, practice exercises, records and radio programs. This led to the independence of some groups of learners who were no longer required to learn strictly from musical schools and resulted in the change in the learning pattern of Thai string ensemble. At present, there are various systems of Thai musical notes that represent new forms of imparting the knowledge of Thai classical music, which have transcended the custom of teacher-centered instruction.
