Siam Sinfonietta is a youth orchestra founded in 2010 by Thai-American composer Somtow Sucharitkul, Thai conductor Trisdee na Patalung, and the Bangkok Opera Foundation.
It was created in order to provide intensive training for young Thai musicians intending to have a serious career in classical music.
It has twice performed in conjunction with the Siam Philharmonic Orchestra: in the Thailand premiere of Mahler's Third Symphony, and at a gala concert in front of CentralWorld in Ratchaprasong, Bangkok, the site of the 2010 troubles, as part of an event to promote "Healing through Harmony."
[4][5] The next year, the orchestra toured in California and performed at Young Euro Classic in Berlin, Germany; this was followed in 2014 by performances in Carnegie Hall and another trip to Berlin, Prague and Abu Dhabi under the auspices of the Thai Ministry of Foreign Affairs.
[6] The orchestra has also appeared on film,[7] first in 2021's The Maestro, a Thai horror film starring Somtow as a murderous conductor, and in the surprising denouement of 2022's Tár (cited as a Filipino orchestra in the screenplay[8]).
