Tallinn Chamber Orchestra (TCO) was founded in 1993 by conductor Tõnu Kaljuste. During the past three decades it has become one of Estonia’s signature orchestras and a welcome guest performer on numerous stages in Europe and all over the world.
 
TCO has gained recognition for its artistically integral programmes, style-sensitive play and mastery of interpretation. The diverse repertoire of the orchestra includes music from the Baroque, Classical and Romantic era; an important part is also held by the musical works of the composers of 20th and 21st century, including less known pieces and premieres. TCO’s musicians are highly rated string players, who also regularly perform as soloists and chamber musicians.

Tallinn Chamber Orchestra has a long-standing cooperation with the Estonian Philharmonic Chamber Choir – joint performances and recordings have gained international fame and recognition for both parties. In 1993, conducted by Tõnu Kaljuste they recorded Arvo Pärt’s Te Deum for the ECM record company. The record earned high ratings from the world’s leading music critics and remained for months in the top ten of record sales. Under the label of ECM, numerous other records have been released, such as Arvo Pärt’s Litany, In Principio, Tractus and Adam’s Lament; also Erkki-Sven Tüür’s Crystallisatio, Veljo Tormis Reminiscentiae and Heino Eller’s Neenia.
Tallinn Chamber Orchestra has also recorded music for Warner Music / Finlandia Records, Carus Verlad, Ondine etc. In 2014, the orchestra released a record with Joseph Haydn’s work (soloist Silver Ainomäe, conductor Risto Joost).
In 2017, the record company Ondine released Tõnu Kõrvits’s CD Lageda laulud (Moorland Elegies) where the music was performed by Estonian Philharmonic Chamber Choir and Tallinn Chamber Orchestra – the record was awarded the Classics Album of the Year at Estonian Music Awards 2018.
