The Köchel catalogue () is a catalogue of compositions by
Wolfgang Amadeus Mozart
Wolfgang Amadeus Mozart (27 January 1756 – 5 December 1791) was a prolific and influential composer of the Classical period (music), Classical period. Despite his short life, his rapid pace of composition and proficiency from an early age ...
, originally created by
Ludwig Ritter von Köchel, in which the entries are abbreviated ''K.'' or ''KV''. Its numbers reflect the ongoing task of compiling the chronology of Mozart's works, and provide a shorthand reference to the compositions. For example, according to Köchel's counting,
Requiem in D minor is the 626th piece Mozart composed, thus is designated ''K. 626''.
Köchel's original catalogue (1862) has been revised several times. Catalogue numbers from these revised editions are indicated either by parentheses or by superscript:
K. 49 (47d) or K. 47d refers to the work numbered 47d in the sixth edition. The catalog was originally

, though revisions made chronological ordering of Mozart's works difficult and as of 2024 a new organizational system is used for the ninth version.
History
In the decades after Mozart's death in 1791 there were several attempts to catalogue his compositions, for example by
Franz Gleißner and
Johann Anton André (published in 1833), but it was not until 1862 that Ludwig von Köchel succeeded in producing a comprehensive listing. Köchel's 551-page catalogue was titled (''Chronological-thematic Catalogue of the Complete Musical Works of W. A. Mozart''). Köchel attempted to arrange the works in chronological order, but many compositions written before 1784 could only be estimated, although
Leopold Mozart
Johann Georg Leopold Mozart (November 14, 1719 – May 28, 1787) was a German composer, violinist, and music theorist. He is best known today as the father and teacher of Wolfgang Amadeus Mozart, and for his violin textbook ''Versuch einer grün ...
had compiled a partial list of his son's earlier works; Mozart's catalogue of his own compositions (begun in February 1784 with
K. 449) allows relatively precise dating of many of his later works. The catalogue included the opening bars of each piece, known as an
incipit
The incipit ( ) of a text is the first few words of the text, employed as an identifying label. In a musical composition, an incipit is an initial sequence of Musical note, notes, having the same purpose. The word ''incipit'' comes from Latin an ...
. Köchel divided the corpus into a main chronology of 626 works, and five appendices ( in German), abbreviated Anh. I–V which comprise:
*I – Lost authentic works
*II – Fragments by Mozart
*III – Works by Mozart transcribed by others
*IV – Doubtful works
*V – Misattributed works
Since Köchel published his original catalogue in 1863 (now referred to as K), the dating of Mozart's compositions has been subject to constant revision. Many more pieces have since been found, re-dated, re-attributed and re-numbered, requiring three revised editions of the catalogue. Subsequent editions – especially the third edition (K) by
Alfred Einstein
Alfred Einstein (December 30, 1880February 13, 1952) was a German-American musicologist and music editor. He was born in Munich, and fled Nazi Germany after Adolf Hitler, Hitler's ''Machtergreifung'', arriving in the United States by 1939. He is b ...
(1937), and the sixth edition (K) by
Franz Giegling, , and (1964) – have reflected attempts to arrange the growing list of works in a more accurate chronological order, according to various levels of scholarship. Because of the confusing renumbering between versions, the ninth edition (K) by
Neal Zaslaw (2024) abandoned the chronological order: all works that were included in a previous edition return to the oldest number they were given, and works newly included in the ninth edition were given numbers past 626, all the way to 721.
The New Köchel Catalog
(2024)
A major shortcoming of K was that there was no room to expand the strictly sequential numbering in the main catalogue to allow for any new discoveries or further reassessment of existing works. For the 1937 edition (K) Einstein (following the analyses of Théodore de Wyzewa and Georges de St. Foix) reassigned some works from the original K appendices into the main catalogue by interpolating numbers with a lower-case letter suffix. In K some of these were, per intervening scholarship, returned to re-structured appendices:
* K. 626a
** K. 626a I – 64 Cadenza
In music, a cadenza, (from , meaning cadence; plural, ''cadenze'' ) is, generically, an improvised or written-out ornamental passage played or sung by a soloist(s), usually in a "free" rhythmic style, and often allowing virtuosic display ...
s by Mozart to his own keyboard concertos
** K. 626a II – Cadenzas by Mozart to keyboard concertos by other composers
* K. 626b – 42 sketches & other fragments by Mozart (replacing K Anh. II)
* Anh. A – Copies by Mozart of other composers' works
* Anh. B – Works by Mozart transcribed by others
* Anh. C – Doubtful and misattributed vocal (C 1–10) and instrumental (C 11-30) works
For example, ''Divertimento for Wind Octet in E'' was numbered K. Anh. 226 in K; Einstein placed it in the K main catalogue as K. 196e, between K. 196 and K. 197; K reassigned it again to the 'doubtful' appendix C as K. Anh. C 17.01; and K reverts to Einstein's assignment as K. 196e (though it is still considered a doubtful work). Some works in Anh. A have been identified since 1965 as by Leopold Mozart. Many works in Anh. C have since been more reliably assigned to other composers, or to Mozart himself.
List of existing Mozart compositions
To maintain as much of the original K-numbering of the list as possible, while re-ordering in the revised, chronological sequence, letters were added to the new numbers. The following list shows the latest edition (K), Köchel's original designation (K), and the sixth edition (K). Other addenda and supplements to the catalogue are marked ''.'' (This has been abbreviated to 'Anh.' in the list below.)

Recordings of the complete works of Mozart have been issued three times: on the occasion of the bicentenary of Mozart's death in 1991, Philips Classics Records released a 180-CD collection in 45 box sets and each CD in a jewel case, ''The Complete Mozart Edition

The Philips collection was made with recordings from world-renowned artists and is of high audio quality.
