Her teachers included Rinaldo Renzo Bossi, Emile Jacques Dalcroze, Andre Gedalge, Giacomo Orefice, Vladimir Vogel, and Ernst Wolff.
[3][4] Rochat lived in Milan from 1922 to 1964, where she published music reviews in several magazines under the pseudonym Jean Durand.
In 1941, the reviews were published as a collection entitled Journal d'un Amateur de Musique.
In 1961, her composition Musica per Archi, opus 26, received the GEDOK (Gemeinschaft deutscher und oesterreichischer Künstlerinnen und Kunstfreundinnen; Community of German and Austrian Women Artists and Art Friends) prize.
Although she composed works through at least opus 34,[4] she destroyed many of her compositions, saying that she “did not want to burden anyone with them.” In 1965, she moved to Zurich, where she joined the Swiss Musicians' Association and lived until her death in 1990.
