Practicing is necessary throughout life, but it is often little questioned, reflected upon, and certainly not utilized to the benefit of those practicing. The experienced music educator Ulrich Mahlert has gathered renowned authors from musical practice and related disciplines for the "Handbook of Practice" he edited. They know the joys and challenges of practicing from their own experiences. From their contributions, a fundamental and thoroughly developed book has emerged on a stimulating and enduring topic. The concise subtitle "Foundations, Concepts, Methods" serves as a program: the volume aims to provide impulses for enjoyable and productive practice. Ideally, appropriately tailored practice contributes to self-awareness, self-criticism, and personal development. If this goal is achieved, then this book has fulfilled its purpose. It is to be hoped that this extensive volume becomes a standard work for all practitioners.
