Within an avant-garde language, Kaija Saariaho stands out for her work in vocal music and above all in stage music, with several operas to her credit. Composers who have stood out in the world of opera have been, among others, the Englishwomen Ethel Mary Smyth (1858-1944) and Elizabeth MaConchy (1907-1994), the Scottish Thea Musgrave (1928) and Judith Weir (1954), the Australian Peggy Glanville-Hicks (1928), the Australian Peggy Glanville-Hicks (1907-1994), and the Scottish Thea Musgrave (1928), among others, the Australian Peggy Glanville-Hicks (1912-1990), the French Germaine Tailleferre (1892-1983), the American Alice Shields (1943) and the Spanish Matilde Salvador (1918-2007), Raquel García-Tomás (1984) and Anna Tena (1994).
Like the latter, Saariaho has frequently used electronic and computer resources. Among the women composers who preceded Saariaho and who composed works with or without electroacoustics were the Americans Hilda Fanny Dianda (1925), Nancy Van de Vate (1930), Elaine Barkin (1932-2023), Alicia Urreta (1933-1987), Gloria Coates (1934), Alicia Terzián (1934) and Jacqueline Nova (1935-1975). Meredith Monk (1942), Laurie Spiegel (1945), Laurie Anderson (1947), Odaline de la Martinez (1949) and Libby Larsen (1950).
On the European continent, Tera de Marez Oyens (1932), Paulina Oliveiros (1932), Teresa Procaccini (1934), Barbara Heller (1936), Constanza Capdeville (1937-1992), Marta Ptaszynska (1943), Joanna Bruzdowicz (1943) and Françoise Barrière (1944) stand out. They are joined by Israel's Ran Shulamit (1949) and Russia's Sofia Gubaidulina (1931).
The Spanish composers who are beginning to venture into electronics are María Luisa Ozaita (1939-2017), Leonora Milà (1942) and Bofill Leví, Anna (1944).
Contemporaries of the Finnish composer are, among others, the American Anne LeBaron (1953), the Romanian Violeta Dinescu (1953) and Adriana Hölszky (1953), and the Swiss Regina Irman (1957).
Composers who follow Saariaho's line are the Spanish composers Diana Pérez Custodio (1970), Iluminada Pérez Frutos (1972), Gloria Rodríguez (1972), Montserrat Torras (1973) and Sonia Megías (1982).
