The Chorus of the Teatro Regio of Torino was established in 1945 after the fire of the Theatre in1936 and the second world war interrupted its activity, becoming, in 1967, the permanent chorus of Teatro Regio. It is made up of around seventy-five singers and is regularly engaged both in productions of the Opera Season and in intense activity around the region for symphonic-choral concerts and “a cappella”.
Since 1993 it has been invited many times to perform with the Rai Orchestra of Torino (which then became the Rai National Symphony Orchestra). From 1994 to 2002 it was directed by Maestro Bruno Casoni. In 1996 it took part in the centenary performance of La bohème by Giacomo Puccini with Luciano Pavarotti and Mirella Freni, broadcast live on television by the Rai. In 1997 it participated in Verdi’s Otello with the Berlin Philharmonic, conducted by Claudio Abbado.
With the Orchestra of the Teatro Regio, it has recorded for Nuova Era The barber of Seville by Rossini and Don Pasquale by Donizetti with Bruno Campanella conducting, and in 1997  Hardy Classic put out a video of Rossini’s Elisabetta, regina d’Inghilterra, conducted by Gabriele Ferro, with singers Lella Cuberli, Daniela Dessì and Rockwell Blake. Under the direction of Bruno Casoni the Chorus of the Regio  reached a stylistic perfection recognised by national and international critics, allowing the group to be considered one of the best at the European level. As evidence of the quality they have reached, one need only consider the performance at the Teatro Regio of the b minor Mass by Johann Sebastian Bach in May 2002, under the direction of Semyon Bychkov. From September 2002 to June 2008 the Chorus has been led by Claudio Marino Moretti.
At present the Chorus is led by Roberto Gabbiani.
In 2004, members of the artistic groups of the Teatro Regio formed the Orchestra Filarmonica ‘900 and the Coro Filarmonico of Teatro Regio, both organizations active in performing symphonic-choral works.
