Here is a book of Music Training for the third year of the 1st cycle. This book is composed of two parts: 1) The first part, of white color, is composed of 14 well structured chapters. Each is the in-depth study of a work (or extract) of different composers and genres (from Bach to Stravinsky through jazz, traditional music ...). The choice is based on the musical and technical aspect while keeping a playful side. The student will progress with pleasure by being the actor of this musical reality thanks to his vocal, instrumental, corporal participation. 2) The second part, divided into three colors, is an add-on that can be used by the teacher depending on the amount of time available. It helps to reinforce the notions acquired in reading (blue pages), rhythm (yellow pages), singing (with one or two voices and canons) listening and theory (pink pages), with texts of authors and basic exercises. This second part is in concordance with the chapters of the first part and will allow a use of this book in the different structures, CRR, CRD, CRC, associative schools ... At the beginning of the student's book, the teacher will, thanks to at the table of contents, get a quick overview of acquisitions. A sound support (optional CD) accompanies the teacher in his educational approach and allows students to hear a wide range of works and instruments.
