With the new printing of Mozart's piano sonatas, Breitkopf & Hrtel offers an insight into the performance practice of around 1900. Since Teichmller took the musical text of the Urtext edition (Breitkopf & Hrtel) and the Mozart Complete Edition as a basis marking all his additions, this edition is not only suitable for historically interested piano teachers, but also for pianists. In addition to fingerings and additional articulations, the musical text also contains examples of the execution of the numerous ornaments. -the publisher
