New edition of the Köchelverzeichnis
Now also available digitally.

The Köchel catalogue, first published by Breitkopf & Härtel in 1862, was a milestone in music history. The Köchel catalogue was fundamentally revised in 1905, 1937 and 1964, demonstrating the enormous progress, achieved by generations of Mozart scholars.

Now the new 2024 edition results are available - in printed form, once again published by Breitkopf & Härtel, and additionally as a digital version. The great composer’s rich, incomparable œuvre is now newly documented and interpreted on almost 1,400 pages. The new Köchel catalogue in a nutshell:

• provides information on incorrect attributions
