The Tampere Philharmonic Choir, founded 1990, is a large mixed choir focusing mainly on major choral works with orchestra. Their most important partner is the Tampere Philharmonic Orchestra, with whom they perform 2–5 major works each year.
The choir has also performed with a number of other orchestras in Finland and abroad, e.g. the Finnish Radio Symphony Orchestra, the Orchestra of the Estonian Theatre, and the State Opera of Plovdiv, Bulgaria.
In addition to famous choral works, the choir's repertoire includes rarities like the Belshazzar oratorio by Georg Friedrich Händel, Robert Schumann's Requiem (both of which were Finnish premieres), Uuno Klami's Psalmus and Einar Englund's Sixth Symphony.
The choir has made three recordings with the Tampere Philharmonic Orchestra: the premiere recording of Sibelius's Press Celebrations Music (ODE 913.2), which received three recording prizes; Einar Englund's Sixth Symphony (ODE 951-2), which received the national Janne Award of the IFPI in 2001; and the 3rd Symphony by George Enescu (ODE 1197-2).
Another important line of repertoire for the Tampere Philharmonic Choir are independent a cappella productions. A cappella concerts have played an important part in the shaping and development of the choir's sound. Their first a cappella recording came out in spring 2002.
The Tampere Philharmonic Choir has an active membership of about 90.
