The International Rostrum of Composers (IRC) is an annual forum organized by the International Music Council that offers broadcasting representatives the opportunity to exchange and publicize pieces of contemporary classical music. It is funded by contributions from participating national radio networks.
The first Rostrum took place in 1954 and involved delegates from the German, French, Belgian and Swiss national broadcasting companies. From then until 2002 the Rostrum's sessions were held at UNESCO's headquarters in Paris, with the exception of 2000 when they were hosted by Muziek Groep Nederland and the Gaudeamus Foundation in Amsterdam. Since 2003, a rotation system has been in place, where the Rostrum is hosted every other year by Radio France and in the intervening year visits a European venue. Starting from 2010 the Rostrum is travelling around Europe by invitation of National Radio Broadcasters. Rostrum in 2020 was postponed until 2021.
Over thirty national radio networks now send delegates, presenting in total sixty or so works each year that have been composed no more than five years previously. Following sessions of listening and discussion, the delegates highlight one of the works submitted (that year's "selected work") and recommend a number of the others. They also highlight one or two works by composers under the age of thirty and recommend one or two others. These selected and recommended works are those most likely to be broadcast or played in concerts sponsored by the participating networks or others that follow the Rostrum's deliberations. All works presented are offered by the European Broadcasting Union to its members via satellite. Copies of recordings, scores and notes featured during the forum are kept at the Gaudeamus Foundation.
From 1991 until 2003 the composer of each year’s selected work was awarded the UNESCO Mozart Medal. Since 2004 the composer of each year’s selected work is awarded the UNESCO Picasso-Miró Medal and the composer or composers under the age of thirty whose work or works are selected are awarded the Guy Huot Bursary for young composers.
Since 2015, the International Rostrum of Composers is part of a large project called Rostrum+ a cooperation project co-funded by the Creative Europe programme of the European Union which aims to rethink the ways in which contemporary music connects with audiences through radio network by exploring new strategies to develop audiences, promote new music, enhance the skills of radio professionals and inspire cooperation between musicians, higher music education institutions and broadcasting companies throughout Europe and beyond.
The selected composer in the General Category of each edition receive a joint commission Radio France / IMC for an Alla Breve composition that are performed by musicians of the Orchestre Philharmonique de Radio France, recorded and broadcast by Radio France in a special program called Alla Breve.
Swedish Radio and IMC jointly commission a work to the composer selected in the “Under 30” category. The composer is invited to Sweden for an introductory 2-day workshop with a local ensemble and then write a work for them which is broadcast live by the Swedish Radio.
