Here are the score and parts to Schumann Piano Quartet. This work is absolutely lovely and underplayed relative to it’s relative the Piano Quintet. The third and fourth movements are absolutely stunning. The third has a gorgeous, wistful, bittersweet and nostalgic feel spun out of an incredible melody that would make any romantic composer jealous. The fourth recombines motives from all the earlier movements and is very difficult to put together as an ensemble, but is a great finish (I believe that the finale to be much more exciting than the quintet, not to put that work down).
