In his Art of Piano Playing, the renowned Russian pianist and teacher Heinrich Neuhaus asserts that the concept of an "artistic image" can give musical meaning to the score, help pianists to understand the musical content of a composition, and help students to find pianistic expression in the details. The concept of artistic image can be applied in pedagogy, guiding young pianists to learn content and organize their practice. The artistic image is the picture of a musical idea and the musical language, which comes from melody, phrasing, musical structure, and the emotional and poetic content. Twelve Children's Pieces of Medium Difficulty, Op. 31, is one of the important works for young pianists by Reinhold Glière (1875–1956). The set has emotional characteristics that allow intermediate young pianists to grasp its rich content and then develop technically. His piano works have been little studied by scholars as part of a pedagogical approach. This pedagogical guide uses the concept of artistic image in Glière's work to help young pianists, or their teachers, prepare this work thoroughly and perform it successfully on the stage.
