Hélène de Montgeroult was a French pianist, composer and pedagogue born in Lyon in 1764 who established her career in Paris during the late 18th and early 19th centuries, writing primarily for the fortepiano within the Classical-to-early-Romantic tradition. Her music and instructional writings display advanced keyboard technique and inventive harmonic language that anticipated aspects of Romantic piano writing, and she produced numerous études and pedagogical pieces that contributed to evolving French piano practice.
