The result of the study shows that every single piece has its own title and implied style which inspires children's imagination towards music. Besides, the length of music is often kept within 48 measures, which is short enough to maintain children's attention during practicing and performing. The spreading range of fingers is set within sixth during the music, which suits children's palm shape. Also, the music is mainly based on ternary form which provides a simple structure with motivated composing strategies of repetition and sequence. All the above shows that he successfully grasped the characteristics of beginner and intermediate piano learners and adopted the regularity and pure nature of music in composition which tends to attract children's interests.

结果发现：每首乐曲都有标题，可藉由标题与提示风格开启儿童对音乐的想像空间；乐曲篇幅短小，多在四十八小节内，配合儿童有限的专注时间，便於练习与弹奏；乐曲中，手的扩张幅度以六度内为主，音程跨距适合儿童手的大小；乐曲结构单纯，曲式组织以三段体为主，动机写作手法以反覆、模进运用最多，也显示卡巴赖夫斯基掌握初、中程度学生的特徵，运用音乐规律性与单纯本质写作易为他们所喜爱的作品。
