Étude Op. 10, No. 6, in E-flat minor, is a study for solo piano composed by Frédéric Chopin in 1830. It was first published in 1833 in France,[1] Germany,[2] and England[3] as the sixth piece of his Études Op. 10. The tempo Andante in 6/8 and con molto espressione indicate a more moderate playing speed than Chopin's other études with the exception of Op. 10, No. 3 and Op. 25, No. 7. This étude focuses on expressivity and chromatic structuring of the melody[4] as well as polyphonic texture.
