Symphony No. 31 (Mozart)
The Symphony No. 31 in D major, K. 297/300a, better known as the Paris Symphony, is a symphony by Wolfgang Amadeus Mozart. It may have been first of his symphonies to be published when Jean-Georges Sieber released their edition in 1779.
The autograph manuscript of the symphony (with that of the alternative middle movement) are preserved in the Berlin State Library.
