Title page of C.P.E. Bach’s Sonaten mit veränderten Reprisen (Berlin, 1760)

In 1759, C.P.E. Bach writes a preface to a special new collection of sonatas: “Dès ce qu’on se répète aujourd’hui, & qu’on reproduit une chose, il est indispensable d’y faire des changemens.” “Making changes” is precisely what his Sonaten mit veränderten Reprisen, Wq. 50, do. Writing out every repeat, Bach indulges in embellishment and variation.

In 1775, Leopold Mozart asks J.G.I. Breitkopf (“the famous bookseller in Leipzig”) whether he might like to publish an opus of keyboard sonatas with varied repeats, “just like C.P.E. Bach’s.” Leopold is pitching the six “Munich Sonatas,” K. 279–284 of his nineteen-year old son, Wolfgang.


As we perform classical keyboard sonatas, do we too feel the pressure of variation? How do we partake in such a practice? A printed score of “Six Sonatas with Varied Repeats” by W.A. Mozart did not materialize. But what might it have looked like?

We will explore these questions during a ten-day workshop around two types of historical keyboards: a 1760s German-style clavichord and a 1786 Andreas Stein fortepiano. To assure sufficient time for hands-on experimenting, six instruments will be available: three clavichords by Joris Potvlieghe and three fortepianos by Chris Maene.

Through coaching, workshops, and seminars we will:

  • Explore and compare playing techniques on the clavichord and Stein fortepiano, with special focus on Empfindsamkeit;
  • Teach ourselves to improvise and compose in galant and classical styles;
  • Gain a more intimate sense of Bach and Mozart as performer-composers;
  • Contextualize the function, form, and performance of a keyboard sonata in a sight-reading culture;
  • Read and discuss C.P.E. Bach’s Versuch über die wahre Art, das Clavier zu spielen (1753);
  • Meet the makers of our instruments;
  • Engage with scholarship on topics like the concept of an opus, the persona of composer-performer, or the materiality of performance;
  • Make all these themes relevant for our performance.

Each participant will play one or more sonatas from C.P.E. Bach’s Wq. 50 as well as create and perform their own Mozart Sonata with Varied Repeats.

In addition to two concerts, on Thursday July 13 (which will be the final day of the Academy), you will have the opportunity of recording your Mozart sonata as part of a professional video production.
