The piece of music once known as Wolfgang Amadeus Mozart's Symphony No. 2 in B♭ major, K. 17, is now considered to be not by him, but by possibly his father, Leopold Mozart.[1] This symphony has been given the number Anhang C 11.02 in the sixth edition of Ludwig Ritter von Köchel's catalogue of Mozart's music,[2] and is now also catalogued as Eisen B♭ 6 (LMV VII:B6) in Cliff Eisen's catalogue of Leopold Mozart's symphonies. It was written for 2 oboes, 2 horns in B♭, and a string section.
The symphony is in four movements in the usual quick–slow–minuet–quick pattern:
The publication of this symphony in the Alte Mozart-Ausgabe, the first collected edition of Mozart's music, shows several points at which smaller, editorially-supplied notes are given, suggesting an unfinished composition. For instance, in "Menuetto I", only the first violin and cello/double bass parts are completed; the second violin and viola parts in their entirety in this movement are editorial additions.[4]
Since K. 17 is now believed not to be by W. A. Mozart, the Neue Mozart-Ausgabe does not include this symphony as part of its edition.
