The article discusses the cycle of didactic pieces by Carl Philipp Emanuel Bach entitled Probe- Stücke, included in one of the most important works of that composer, i.e. Essay on the True Art of Playing Keyboard Instruments. The text, which was first published in 1753, to this day remains a valued source of knowledge about the period and a helpful support in the process of education. It seems that the cycle of compositions included with the essay is little known and there are very few sources where we can find information about it. In this respect, practical playing schools by Johann Sebastian Bach are much more popular and are used frequently in music education. It is hardly surprising as today the Leipzig cantor is duly regarded as one of the greatest composers in the history of music. However, the renaissance of the creative output of his son Carl Philipp Emanuel that we observe nowadays, seems to be the right moment to pay attention of music lovers also to the collection of didactic works of that composer. They may turn out to be the key to understand his compositions and also an important element for the field of learning to play keyboard instruments. The cycle includes a complete presentation of genres, various playing techniques, articulations, ornaments, and each part represents a diffe- rent character, a different affect. Listed elements, combined with the composer’s individual style, make the Probe-Stücke a perfect material for teaching keyboard instrument playing. In the article we will find a discussion on the works in the context of the composer’s remarks included in the theoretical part of the essay. Further on the author focuses on the analysis of the compositions in the Probe-Stücke and attempts to evaluate the usefulness of the cycle for teaching purposes as well as its artistic qualities.
