Schola Cantorum Stuttgart, founded in 1960 by Clytus Gottwald, was a professional vocal ensemble based in Germany. The group consisted of 16 to 18 singers and focused on both classical vocal polyphony and contemporary music. Under Gottwald's direction, Schola Cantorum performed over 80 premieres and first performances of choral works, collaborating with notable composers such as Pierre Boulez, Brian Ferneyhough, and György Ligeti. Their repertoire included pieces by Ligeti that were featured in Stanley Kubrickâs film 2001: A Space Odyssey. The ensemble released several albums, including Atelier Schola Cantorum (1993) and Schola Cantorum & Neue Vocalsolisten Stuttgart (2001). Gottwald directed the group until its dissolution in 1990.
