Musique concrète
After the war, she read at the Conservatory of Music, first as a pianist, but because of the after-effects of her stay in Frøslevlejren she could not do this and trained instead as a composer. In 1952 she heard a Danmarks Radio programme on Musique concrète and its creator Pierre Schaeffer. It reminded her of her own childhood conception of sounds and timbres. Via family in France, she contacted the French radio RTF and Schaeffer. She got the chance to see studies on RTF and Pierre Schaeffer had his workshop and got an appointment to get sent home material. In the same year she read Schaeffer's book "À la Recherche d'une musique concrete" (On the trail of concrete music).
