Franziska LeBrun

Francesca Lebrun was a celebrated German soprano associated with the court at Mannheim, as well as an accomplished composer of sonatas. As a singer, she was renowned for her vocal dexterity and was highly sought after by such notable composers as Anton Schweitzer, Ignaz Holzbauer, and Antonio Salieri to sing the lead roles in their most challenging operas. As a composer, her twelve sonatas for piano or harpsichord with violin accompaniment, six each in opus 1 and opus 2, were first published in London, England, in 1779–1781, with further editions in London, Paris, and several German centers. The opus 1 sonatas are available in commercial recordings.
