After becoming fascinated by the harp at a concert, Rosetta Schade began harp lessons at the youth music school in her home town of Reutlingen.
 
She was subsequently accepted into the renowned class of Prof. Xavier de Maistre and Anaëlle Tourret at the Hamburg University of Music and Theatre, where she successfully completed her Bachelor's and her Master's degree. During an Erasmus stay at the Pôle Supérieur des Conservatoire à Rayonnement Régional in Paris, she received important impulses for her playing from her teachers there, Ghislaine Petit-Volta and Nicolas Tulliez. Rosetta is currently studying with Prof. Andreas Mildner in the postgraduate masterclass program at the Würzburg Univeristy of Music.

In addition to her studies, Rosetta Schade attended numerous masterclasses with renowned harpists such as Letizia Belmondo, Marie-Pierre Langlamet, Margit-Anna Süss, Fréderique Cambreling, Fabrice Pierre and Catherine Michel. 

Rosetta Schade has been honoured with several first prizes and special prizes. These include the competition of the German Harpists' Association and the Collegium 21 International Harp Competition for Contemporary Music in Paris. In 2022, she takes part in one of the world's largest harp competitions, the Bloomington International Harp Contest in the USA. 

Rosetta Schade performs as a soloist at renowned festivals in Germany, France and the Netherlands. She is regularly invited as a substitute by numerous orchestras, including the Bremen Philharmonic Orchestra, the Hamburg Philharmonic State Orchestra and the Hamburg Symphony Orchestra, and is a member of the Lucerne Festival Contemporary Orchestra, the NDR Youth Symphony Orchestra and the Bayreuth Festival of Young Artists. Since the 2024/2025 season, she has been engaged as an academy member for the Oldenburg State Theatre.
