Höstsonaten - Autumn Sonata is a new Finnish opera based on the film script of Ingmar Bergman. The main theme in the Autumn Sonata is the complex relationship between a mother and a daughter. ”In the end the daughter gives birth to her mother” – that’s how Ingmar Bergman envisioned the cathartic final resolution between concert pianist Charlotte Andergast and her daughter Eva. "My dear Ingmar, it has after all gone down in history as one of your best, it’s a real classic! Anyone who’s ever been moved by Autumn Sonata will remember it forever – and there are so many of us!" writes the librettist Gunilla Hemming.
Love, death, nature and the mystery of life are themes that recur in Kaija Saariaho’s music every since her youthful works, and they maintain a strong presence today, in the 2010s. At the same time, the key element in her music – tonal colour – has become increasingly significant: the lucid is more lucid than ever, and the dark hues are darker still.
