The Symphony No. 28 in C major, K. 200/189k, by Wolfgang Amadeus Mozart is his last piece in the "Salzburg series".[1] The exact date of composition is uncertain because of Mozart's unclear handwriting; the month is clearly November, but the day can be read as 12 or 17, and the year has been read as 1774, but more recent research points to 1773.[2]
The symphony was written early in Mozart's oeuvre, following the example of the twenty-fifth symphony.
