This series, with a clear and lively presentation and varied exercise styles, is built around songs, traditional music, or excerpts from classical works. It follows the curriculum of a first cycle of musical training over 4 years and is intended for both children and adults. For each level, the educational content is divided into two volumes. One volume for the oral part: singing, listening commentary, theory, note reading, rhythm reading… One volume for the written part: writing, dictation of notes and rhythms, theory exercises… These two volumes (oral, written) are independent and can also be used together.
