Chopin three new etudes trois nouvelles etudes no 1 f minor

Frédéric Chopin wrote his Trois nouvelles études (“three new studies“) for piano in 1839, as a contribution to “Méthode des méthodes de piano“, a piano instruction book by Ignaz Moscheles and François-Joseph Fétis. They are often erroneously described as posthumous. In general, these études display little of the technical brilliance of most of the composers Op 10 and 25, though they do retain Chopin’s original formula for harmonic and structural balance. Played by Anastasia Huppmann in Vienna. Many thanks
