The Swiss Society for Contemporary Music (ISCM Switzerland) is the national section of the International Society for Contemporary Music ISCM and promotes the national and international exchange of contemporary music with a special focus on Swiss composers. Members of ISCM Switzerland are regional ISCM groups and ensembles, notably from Basle, Bern, Lausanne, Neuchâtel, St.Gallen, Lucerne, Zentralschweiz and Valais.
ISCM Switzerland was founded 1922 by Werner Reinhart. On the initiative of Paul Sacher it shared the office with the STV/ASM (Swiss Musicians Association) from 1946-2001. The Swiss ISCM sections organised the „World Music Days“ in 1926 (Zürich), 1929 (Genève), 1957 (Zürich), 1970 (Basel), 1991 (Zürich) and 2004 (all around Switzerland).
At the dawn of the 21st Century, the range of music that we have access to is greater than it has ever been, through the enormous technological advances of the 20th Century. This means that a definition of what "contemporary music" might be is difficult, as composers are being influenced by more kinds of sounds - musical and other - than ever before. Performers are presenting contemporary music in many different kinds of environments to reach their audiences, and there is now a continual redefinition of the relationships which exist between composers, performers and the audience. The International Society for Contemporary Music (ISCM) is an important international network of members from around fifty countries, devoted to the promotion and presentation of contemporary music - the music of our time. ISCM has had a distinguished history. From its foundation in Salzburg in 1922 (with Bartok, Hindemith, Honegger, Milhaud, Ravel, Berg, Schönberg, Strawinsky and Webern as co-founders), a receptiveness to aesthetic and stylistic diversity has been a characteristic of the Society. Each year, ISCM presents the World Music Days Festival, hosted by one of ISCM's members, which provides a feast of contemporary music across a broad range of contemporary practice. ISCM Sections are independent organisations which co-ordinate the endeavours of furthering contemporary music in a country.
