Book excerpt: Meet the inventors and innovators who defined American music history. A radio repairman imagined inventing the electric guitar. The inventor of 3-D glasses envisioned an electric organ in every home. And a German carpenter immigrated to New York City with the dream of designing the greatest piano in the world. From Steinway pianos and Moog synthesizers to Zildgian cymbals and Martin guitars, noted music writer VanHeke offers a fascinating, insider view of the personalities and perseverance that led to some of music's most important innovations—from classical to jazz to rock. This ALA Notable Children's Book includes photos, source notes, and glossaries.
