Chopin: Trois nouvelles études (Three New Studies)

Frederic Chopin's Trois nouvelles études (Three New Studies), B. 130, were composed in 1839 as a contribution to Méthode des méthodes de piano, a piano instruction book by Ignaz Moscheles and François-Joseph Fetis. These études are often erroneously described as posthumous works. They are less technical than the composer's Opus 10 and Opus 25 etudes, but they retain Chopin's original style of harmonic and structural balance.

The first of the Trois nouvelles études is an intimate piece in F minor. It develops students' facility with 3-on-4 polyrhythms.
