Klaviersonaten Nr. 21 F-dur Und Nr. 49 Es-dur = Sonatas For Piano No. 21 In F Major And No. 49 In E Flat Major / Arietta Con Variazioni Es-dur / Fantasia C-dur

Released in 1959 by Deutsche Grammophon, this recording features the French pianist Monique Haas interpreting a selection of Joseph Haydn's piano sonatas and works, including the Sonata No. 21 and the Sonata No. 49. The album was produced during a period when Deutsche Grammophon was aggressively expanding its stereo catalog, utilizing the label's high-fidelity recording techniques to capture Haas's precise, nuanced, and structurally disciplined approach to the Classical repertoire.

Monique Haas was highly regarded for her scholarly and clear-headed interpretations of both contemporary music and the Classical canon. In this recording, her performance reflects a shift toward a more modern, objective style of playing that eschewed romantic sentimentality in favor of clarity and rhythmic vitality. The cover design adheres to the classic, austere aesthetic favored by Deutsche Grammophon at the time, prioritizing minimal typography and a clean presentation that signaled the technical and artistic prestige associated with the Yellow Label brand.
