Book 4 reinforces and revises all concepts learned in Books 1-3. It contains attractive repertoire in various styles and from different periods. Each piece has a comprehensive preparation section covering the musical, technical and structural matters which will be encountered. The aim is to cultivate critical thinking and musical awareness in the student. As in previous books, the child is actively involved through the use of writing, colouring, tracing and pasting, thereby making the preparation an enjoyable activity. The standard of the repertoire approaches that of Grade 1.
