Mas Sardi (December 1910 – 21 October 1953) was an Indonesian composer and musician notable for being the country's first professional music supervisor.

[1] He was educated at a Lagere School, but also studied the violin with his father, the leader of the Norma Orchestra in the palace of Sultan Hamengkubuwono VII.

Sardi played for Jonocy, but eventually left to tour Central Java with Kunstkring; he would sometimes lead the orchestra at the Sultan's palace, if his father was unavailable.

[5] During the next two years Sardi prepared music for several more JIF productions, including Rentjong Atjeh, Srigala Item, and Matula.

On 17 August 1945 Indonesia proclaimed its independence, and by the end of the year the returning Dutch colonial government had occupied the capital, Jakarta.
