Composers
Twenty-five composers, every one of them in the hall for their own premiere.
Composer · Denmark
Alma Ravn
Writes for orchestras the way other people write for rooms — she asks how far apart the players can sit before an ensemble stops being one. Her 2025 piece for divided strings was performed with the two halves in separate buildings.
Opening nightWed 15 April · Rudolfinum
On distance and ensembleThu 16 April, 11:00
Commissioning without a budgetSat 18 April, 09:30
Composer · Czech Republic
Teodor Vlasák
Spent six years transcribing the sound of Prague's tram network before writing a note of his own. The resulting cycle uses the exact pitches of eleven junctions, and he still refuses to say which ones.
Orchestral seriesThu 16 – Fri 17 April
Field recording as scoreFri 17 April, 11:00
Composer · Japan
Hiroko Serizawa
Her scores specify silence in seconds rather than rests, which players describe as either liberating or unbearable. She has written that a hall's empty sound is the only instrument she trusts completely.
Opening nightWed 15 April · Rudolfinum
Notating silenceSat 18 April, 11:00
Composer · Brazil
Carla Ferreira dos Santos
Writes fast, loud, and for far too many percussionists. Her commission for the opening night calls for nine players and a hall that can take it, which is why it is being performed in Karlín rather than upstream.
Opening nightWed 15 April · Rudolfinum
Writing for too manySun 19 April, 11:00
Composer · Iceland
Sigrún Halldórsdóttir
Works almost exclusively with amateur choirs, on the grounds that professionals have already decided what a voice should sound like. Her closing commission is for the festival chorus and 300 members of the public.
