According to his teacher, young Les Paul—who preferred playing piano by ear over sight reading—would "never be musical." Undeterred and with his mother's support, Paul pursued his interests, musical and otherwise. After designing and building a radio set, he learned to play guitar, banjo, and harmonica, performing for audiences that expressed their wish to hear the music better. Through trial and error, Paul created contraptions to amplify the sound of his guitar—but the guitar's vibrations caused unwelcome feedback. A steel rail and an electric guitar prototype (called the Log, because of its shape) led to a design that resembles modern-day instruments. In Helquist's expressive oil paintings, Paul's music is visualized as colorful orbs and swirling lines. Good ideas require persistence, determination, and lots of experimentation, Tomsic implies through Paul's story. A note from the author explores Paul's contributions to the world of music in greater detail. Ages 5–8. (Apr.)

Gr 2–5—If your child regularly took apart machines in your home or trimmed down a tread on your stairs to make it sound better, how would you react? Fortunately for musicians and music lovers, Les Paul's mother encouraged, even praised, his efforts. From a young age, Les was curious about sound as it relates to music. His initial attempts to learn to play the piano ended with the teacher declaring, "Lester will never learn music…" but a mail-order guitar and a wooden harmonica proved to be just the ticket to launch his ever-widening curiosity about how to improve the sound so it would reach all the way to the back of crowds that came to hear him play. Each performance venue produced additional problems to solve, leading to more and more tinkering with found objects. His persistence and creativity paid off, as he is credited with numerous inventions that have made today's recorded music possible. Paul's story is delightfully told in folksy, familiar language, with numerous onomatopoeias to represent the sounds he produced. There is additional back matter that adds more detail to illuminate his amazing career accomplishments. Helquist's illustrations, created with colorful oils, are equally delightful and pleasant. Text and illustrations radiate exuberance and joy. Readers will marvel at the perseverance and ingenuity Paul demonstrated throughout his life. VERDICT A strong addition to inspire would-be inventors, and an excellent choice for STEM programs and biography collections.—Maggie Chase, Boise State University, ID
