Anna Ķirse (*1988) is a Latvian composer working in the areas of chamber music, opera, music for choir, instrumental solo pieces and electroacoustic music. Fascinated by the most intricate properties of sound, she approaches it as a live organism that embodies a musical form in itself. Her work is often created in close collaboration with musicians, exploring the finest timbral, textural and technical possibilities of each instrument that eventually lead to meticulously designed sonoric architectures. Inspired by the mysteries of nature, she steps with it into a conversation through her music, colliding disciplined rationality and scientific research with feminine intuition and sensitive plasticity. In 2019 her Tree Opera. Windthrow for eight voices, chamber ensemble and electronic track was premiered in Finland by Latvia Radio Choir, chamber ensemble and Swedish Paetzold contrabass recorder player Anna Petrini. Anna is currently working on a composition for symphonic orchestra and large choir Carmen Sibyllae (Song of the Sibyl), based on Virgil’s 4th Eclogue, anticipated premiere in 2021.
