My Music Box is a complete book for a second year of music education. He approaches all notions by learning traditional or original songs and discovering a varied repertoire. In order to allow the child to immerse himself in a living musical context and to assimilate durably the notions, all the proposed texts have an audio support. The accompaniments of the songs are available on the educational space of Editions Billaudot's website and the musics of the repertoire on the Deezer platform. The book, in 20 lessons, has the following sections: I sing / I dance, I listen, I read and some at home for personal work. The close link between songs, prescriptions, recognition and deciphering allows the child to make melodic relationships lastingly aware. The reading is approached in a relative way in the first lessons. The proposed rhythms are played with a sound support. This approach makes it possible to make rhythm alive, in connection with a musical reality (phrasing, articulation, perception of sound movement).
