Coordinate reading of notes and rhythms on musical texts in treble and clef keys. This book is for beginners children and adults in first year of musical training and beginners pianists. Composed of two booklets of 28 lessons each (reading notes and reading rhythms), it offers an immediate application of the technique to the practice of music while ensuring an "eye-ear" relationship. The preparatory exercises lead to one or more summary texts of the new acquisitions of the two volumes, conceived in close correspondence. In addition to deciphering, musical texts allow for audition work, and constitute a repertoire of 105 titles to study, play, sing, memorize and listen to.
