First, we will never know how many exactly he wrote, because several symphonies are of doubtful authenticity and it's extremely unlikely that we will ever solve this problem. Second, we don't know many might have been lost. Third, if Mozart extracted three or four movements from an orchestral serenade to perform as a symphony, does it count as a separate symphony? Forth, many of his operatic overtures were performed as symphonies, sometimes with a new ending, sometimes withough changes. Should they be counted among symphonies? "41" is the number of symphonies published in the main part of the now obsolete 19th century complete edition of Mozart works. Further symphonies were published in the additional series of the same edition. Out of those 41 three are not by Mozart, and quite a bunch may very well be not by Mozart, either. Furthermore, a couple of symphonies were found since the old edition was published. -Margaret [log in to unmask]
