(…) The workbook is a useful addition to the growing number of resources for the study of extended techniques now available. The well-written, approachable preface sets the tone of the book, giving a playful approach to modern techniques and providing a palette of colours than can be explored at will. Dehnhard's approach to improvisation is encouraging and supportive, providing ideas and suggesting ways to develop general playing skills through taking risks and trying new things. (…) The material is well presented, with clear fingering diagrams. A range of exercises is included which will be suitable for intermediate players. The level of these exercises means that this book is ideal for everyone except for complete beginners, and provides an excellent starting point for anyone who wants to explore the extended possibilities of the flute, from children to adult amateurs. (..) One of the most useful aspects of this book is the explanation and musical examples for flute beatboxing (fluteboxing). This provides an excellent opportunity to explore the technique in a way which is easy to understand and clearly explained. The DVD contains examples of all of the techniques, as well as recordings of Dehnhard performing his own works, which also appear in the workbook. Dehnhard's music is light-hearted, and the inclusion of these pieces provides an enjoyable context for students to practice the techniques. (…) The book is ideal as teaching material, as well as for those who want to explore on their own. Highly recommended.
