Étude Op. 10 No. 3, in E major, is a study for solo piano composed by Frédéric Chopin in 1832. It was first published in 1833 in France, Germany and England as the third piece of his Études Op. 10. This is a slow cantabile study for polyphonic and legato playing. Chopin himself believed the melody to be his most beautiful one. It became famous through numerous popular arrangements. Neither "Tristesse'" (sadness) nor "Farewell" is a name given by Chopin.
