The Thais had instruments of their own and some were from China such as the khim dulcimer,
malaw cymbal and klawng jin drum. The music of India had penetrated into the Mon (southern Burma) and Khmer (Cambodia) cultures previously. Later, the Thais also came in contact with Indian music. They successfully copied many of the Indian instruments. The Thai's also created their own instruments from this interaction, namely the phin, sang, pichanai, krachappi, chakhe and thon. These are mentioned in one of the oldest books to come out of Thailand called the Tribhunikuthai and also on a stone inscription called the sila-ja rerk created during the reign of king Ramkhamhaeng who was considered the father of the nation during the Sukhothai period 1283 A.D. (Sukhothai translates as Dawn of Happiness since they overthrew the Khmer rulers).
At this time they adopted some instruments such as the glawng khaek from java, the klawng malayu from Malaysia, the perng mang from the Mon people and the glawng yao from Burma.
