Mozart's symphonic production covers a 24 year interval, from 1764 to 1788. According to most recent investigations, Mozart wrote not just the 41 symphonies reported in traditional editions, but up to 68 complete works of this type. However, by convention, the original numbering has been retained, and so his last symphony is still known as "No. 41". Some of the symphonies (K .297, 385, 550) were revised by the author after their first versions.

Childhood Symphonies (1764-1771)

These are the numbered symphonies from Mozart's early childhood. It should be noted that there are also a fair amount of unnumbered symphonies from this time period.

Salzburg Era Symphonies (1771-1781)

These symphonies are sometimes subcategorized as "Early" (1771-1773) and "Late" (1773-1775), and sometimes subcategorized as "Germanic" (with minuet) or "Italian" (without minuet). None of these were printed during Mozart's lifetime.

Although not counted as "symphonies" the three Divertimenti K. 136-138, in 3-movement Italian overture style, are sometimes indicated as "Salzburg Symphonies" too.

Symphony No. 14 in A major, K. 114 (1771)

Symphony No. 15 in G major, K. 124 (1772)

Symphony No. 16 in C major, K. 128 (1772)

Symphony No. 17 in G major, K. 129 (1772)

Symphony No. 18 in F major, K. 130 (1772)

Late Symphonies of Mozart (1791-1791)

Symphony No. 31 "Paris" in D major, K. 297 (K. 300a) (1778)

Symphony No. 32 "Overture in the Italian style" in G major, K. 318 (1779)

Symphony No. 33 in B-flat major, K. 319 (1779)

Symphony No. 34 in C major, K. 338 (1780)

Symphony No. 35 "Haffner" in D major, K. 385 (1782)

Symphony No. 36 "Linz" in C major, K. 425 (1783)

Symphony No. 37 in G major, K. 444 (1784)

For years this was categorized as a Mozart symphony, but later scholarship determined that it was actually composed by Michael Haydn (No. 25), and Mozart wrote only the slow introduction for it.

Symphony No. 38 "Prague" in D major, K. 504 (1786)

The three final symphonies (Nos. 39-41) were completed in about three months in 1788. It is quite likely that he hoped to publish these three works together as a single opus, although actually they remained unpublished until after his death. One or two of them might have been played in public in Leipzig in 1789.
