Madame Hélène de Montgeroult (1764–1836) lived in a time when significant historical events were shaping France and Europe. Montgeroult's musical oeuvre is distinguished by its interpretive versatility. The collection of nine sonatas presented here spans from 1795 to 1811. The three sonatas that make up her Op. 1 are three distinct pieces, each with its own mood. The Op. 2 set was engraved in Paris in 1800, with reprints issued in the ensuing years testament to its success at the time. It can be seen as an expansion of Op. 1's stylistic language, sharing the same compositional features, but greater in length. With the last three sonatas, Op. 5, published by Érard in 1811, Montgeroult rose to mastery. These sonatas are considerably longer and more complex in their formal structure than their predecessors. Overall, the three sonatas in the Op. 5 set expand the form while retaining a Classical-like structure, comparable to later Clementi sonatas or those of other composers of the time, and forecasting the later experimentations of the Romantic generation.
