A.M. Maccheroni developed a music education approach for preschool- and elementary school-aged children using the Montessori Method. To clarify the tenets of Maccheroni’s musical teaching method, we focus on her Music Book. The Music Book consists of 6 volumes; in this study, we start by analyzing Music Book: Melody (Vol. 5), intended for children over 5 years old. As a result of our study, the following becomes clear;1) Music Book: Melody (Vol. 5) aims to increase children’s capacity for music composition and appreciation, 2) Music Book: Melody (Vol. 5) builds on the techniques shown in earlier volumes. In other words, children acquire the learning contents through repetition.
