Phleng chāt Thai (เพลงชาติไทย) is Thai for "Thai national anthem". The shorter title Phleng chāt (เพลงชาติ) is also used. The music was composed in 1932 by Thai musician Phra Chenduriyang and it was adopted later that year without lyrics. Then in 1939, when the country's name was changed from "Siam" to "Thailand", lyrics (words) written by Luang Saranupraphan were made official after winning a competition.
