The Vienna Boys Choir is made up of 100 choristers between the ages of nine and fourteen, divided into four touring choirs. Each choir spends nine to eleven weeks of the academic year on tour. Together, the choirs give around 300 concerts each year, attended by almost half a million spectators around the world. The choir regularly tours Europe, Asia and Australia, and the Americas. The choir’s first journey to Chile took place in 1936. On Sundays, the boys perform with members of the Vienna Philharmonic Orchestra and of the Vienna State Opera Chorus in Vienna’s Imperial Chapel, as they have done since 1498. In 2012, the choir opened its own concert hall, MuTh; the state-of-the art facility seats 400 and has proven highly popular with both artists and audience. The choir’s repertoire includes everything from medieval to contemporary music. Motets and lieder form the core of the touring repertoire, as do the choir’s own arrangements of Viennese music. The choir also performs children’s operas and world music.
