When during the season 1999/2000 only the older members of the children’s choir were needed for various operas and operettas such as "Simplicius" or "The Rose from The Garden of Love," a new group, specific for this, was formed. During the frequent rehearsals, the ensemble soon began to develop its own dynamics and arose definitively from the children’s choir in July 2002: The Youth Choir of the Opera Zurich was born informally and appeared again on stage for the remount of "Hansel & Gretel" in 2003. At the beginning of the season 2010/2011 the name was changed to "SoprAlti of the Opera Zurich."
Today, the choir is an integral part of the Zurich Opera House. It currently consists of
about 20 enthusiastic singers aged 18 to 30 years old.
Each season it has an average of between 20 and 60 performances. It supports the children's choir, or performs together with the supplementary and the professional choir of the opera. In some operas, it also has its own parts, such in as "The King’s Children" (children of the broom-maker), "Le Cid" (young girls) or "The Cunning Little Vixen " (chicken).
Concerts, external guest performances, exhibitions on religious holidays or closed events
for companies and foundations, are part the annual program outside of the opera as well
as appearances in the major concert halls (the latter mostly with the other choirs of the
opera house, for example for Verdi's Requiem, the 9th symphony of Beethoven or the Missa Criolla
de Navidad by Carlos Irigaray).
Although the focus of the choir is on opera and classical music, it is flexible in the selection of pieces. Concert programs cover a broad spectrum from church music and classical music to folk and film music to contemporary music.
Many of the members are also musically active outside the Opera House, be it in other choirs, an orchestra, or in their studies.
The intense friendships that are maintained in the choir beyond the musical commitment lead to an effortless attuning of the singers to each other. That way, the chorus is constantly evolving and is able to also meet the requirements of the repertoire.
