For the following symphonies, the unusual and dual numbering of these works is mainly due to revisions and updates to the Köchel catalogue,
as well as the inclusion of incomplete pieces, overtures, and symphonies of dubious attribution. Mozart’s youthful works, in particular,
were relocated within the catalogue as new evidence regarding their authenticity and chronology came to light.

The following symphonic pieces have not been used for this video due to questionable authorship by Mozart:
Symphony No. 2 in B flat major KV 17: attributed to Leopold Mozartt, his father;
Symphony No. 3 in E-flat major, K. 18: spurious, by Carl Friedrich Abel;
Symphony No. 15 in G major, K. 124: the relative simplicity of the form suggests that it could have been an early piece, possibly influenced by his family and educational environment;
Symphony No. 23 in D major, K. 181/162b: there are doubts as to whether Mozart composed it entirely by himself;
Symphony No. 26 in E-flat major, K. 184/161a: certain parts of the work may have been influenced or complemented by other composers;
Symphony No. 32 in G major, K. 318: this piece was created more as an overture in symphonic form, possibly with collaboration from other composers or external influences;
Symphony No. 37 in G major, K. 444/425a: attributed mostly to Michael Haydn.

Enjoy it!!
