The Compendium of Improvisation provides important source texts on the improvisational practices of the 17th and 18th centuries for teaching historical keyboard instruments, aimed at a broader audience. It combines insights from recent music theory and the associated rediscovery of the Neapolitan Partimento practice, along with the continually evolving methodological ideas and concepts of the authors. The individual articles link excerpts from sources, musical examples, analyses of preserved compositions, and practical exercises to create a vivid picture of baroque improvisational art. However, the collection does not aim to formulate a consistently structured school of improvisation. Instead, it seeks to open up as many different approaches to style-bound improvisation as possible, with methodological ideas rooted in historical models.
