This book offers a musical reinterpretation of Gustav Holst's The Planets, combining children's narrative, illustration, and sound to introduce young children to classical music. Throughout the story, two siblings, Helen and Tim, embark on an imaginary journey through the solar system from their rocket beds. They travel through landscapes such as the peaks of Mars and the asteroid belt, until they return to Earth at dawn. In each scene, pressing a button activates an orchestral excerpt from Holst's famous suite, fostering an interactive and sensorial experience. At the end of the book, a short biography of the composer, accessible musical explanations about each piece, and a glossary of musical terms are included, integrating learning and enjoyment. Part of The Story Orchestra collection, this work is designed to bring classical music closer to children through illustrated stories and sound fragments that enrich reading. Language: English.
