The Piano Quartet in E♭ major, Op. 47, was composed by Robert Schumann in 1842 for piano, violin, viola and cello. Written during a productive period in which he produced several large-scale chamber music works, it has been described as the "creative double" of his Piano Quintet, finished weeks earlier. Though dedicated to the Russian cellist Mathieu Wielhorsky, it was written with Schumann's wife Clara in mind, who would be the pianist at the premiere on 8 December 1844 in Leipzig.
