Piano playing school by a prominent educator - professor at the Conservatory of Warsaw. The edition is divided into 3 parts:

• Part I: The student is introduced to notation in G (treble clef), rhythmic values (whole note, half note, and quarter note) and their corresponding rests, as well as chromatic notes (sharp, flat).
• Part II: Notation in F (bass clef), the rhythmic value of the eighth note and the importance of the key next to the note.
• Part III: Devoted to the introduction of finer values, trills, different tonalities using chromatic notes with keys.

A valuable addition is the 'Appendix', which includes essential knowledge of music theory.
