Nanette von Schaden was born in 1763 as the illegitimate daughter of Leopold Count Pranck (1728–1793), director of the Salzburg Court War Council and Walburga Stadler in Ebelsberg, Upper Austria (now a district of Linz).
At around the age of eleven, she moved to Vienna with her mother and received a quality education, including piano lessons, in the home of Imperial Court Councilor Friedrich von Mauchart (1736–1781).
In 1779, she married Joseph von Schaden (1754–1814), a court councilor from Wallerstein, and settled with him in the Wallerstein residence, where she soon gained an excellent reputation as a pianist and performed with the Wallerstein court orchestra. In 1787, the Schadens moved to Augsburg, where Joseph von Schaden took up the position of imperial city councilor.
In 1787, she made the acquaintance of Ludwig van Beethoven. In the same year, she also wrote her first composition, a small rondo. By 1788, two piano concertos had been published, which she probably wrote together with Antonio Rosetti.
In early 1793, Nanette von Schaden separated from her husband and moved with her two daughters, Maria Anna Antonia (1784–1819) and Josepha Amalia (1786–1843), to Regensburg to live with her father, where she died in 1834.
