Werner Kaegi (born 17 June 1926) is a Swiss electronic composer, musicologist and educator. During the 1960s, he promoted electronic music in his home country. In the 1970s, as a composer and researcher at Utrecht's Institute of Sonology, The Netherlands, he developed pioneering programs in the field of computer-generated music. Early life Kaegi was born in Uznach, in the St. Gallen canton as the third child of Heinrich Kaegi and Clara Kaegi-Schlaepfer. In their parental home he came into contact with classical music literature at an early age because a lot of music was being played at home. His father in particular was a passionate amateur violinist. His sister played excellent piano, and his brother played violin, viola and flute. The young Werner soon proved able to arrange pieces for the house concerts. From six years he received clarinet and piano lessons. He studied mathematical logic and music in Zürich, Heidelberg and Basel, and music composition in Zürich, Basel, Salzburg and Paris. His music teachers have included composers Paul Hindemith, Arthur Honegger and Louis Aubert. In 1951, blending his interests for mathematics and music, he received his doctorate with a study of the structure of Johann Sebastian Bach's Inventions and Fugues. Kaegi discovered Pierre Schaeffer, musique concrète and the GRM radio broadcasts in Paris in 1951, yet his 1950s compositions are for traditional instruments; Ariadne in Zürich is for clarinet and piano 4 hands, Miniaturen, for oboe, bassoon and cimbalom, while the 1956 Sonate is for clarinet and piano. During the next decade, however, Werner Kaegi embraced electronic music and became a pioneer of Swiss electroacoustic music, predating other composers in the field, such as Bruno Spoerri and Rainer Boesch. At Centre de Recherches Sonores (1963–1970) From 1963 to 1970, Kaegi worked at the Centre de Recherches Sonores, the electroacoustic music studio of Radio Suisse Romande in Geneva. There he started composing electronic and tape music, including pieces such as Éclipses (1964), L'Art de la Table (1964), and Entretiens (1965). At the C.R.S., Kaegi created several radiophonic works; such as La Porte Noire in 1964 and Zéa in 1965. In the late 1960s, Kaegi wrote several essays on electronic music, including the influential book Was ist elektronische Musik?, ("What Is Electronic Music?"), which was published in 1967 in Zurich, Switzerland, and also became a film for Swiss television. This period of electronic music championing culminated in 1971 with the publication
