  ==Composition date trivia== String Quintet in C major, D. 956, op. posth. 163, is a piece of chamber music written by Franz Schubert. It was composed shortly after his Ninth Symphony during the summer of 1828, two months before his death  this seems to suggest the 9th was also composed (or at least finished) in '28, whereas the 9th Symphony page suggests it was the 10th that was started/worked on during '28, and the 9th was finished 2 years earlier.. can someone please clarify?    :Thanks. I didn't even notice the mistake. I've now corrected it. For more information read in the symphony's article.
