Centuries ago, a young Italian monk named Guido longed to find a way to write and teach music. Eventually, he created the musical scale, using the words Do-Re-Mi-Fa-Sol-La-Ti-Do... one syllable for each note. Though the other monks thought it was a waste of time, Guido's music couldn't be silenced. His discovery remains the foundation for learning music today, and inspired the famous song "Do-Re-Mi," which Julie Andrews sang in the beloved movie The Sound of Music.

This richly illustrated picture book from beloved icon Julie Andrews and her daughter, bestselling author Emma Walton Hamilton, introduces readers to the remarkable story of Guido d'Arezzo's development of musical notation. In addition to the lyrics of "Do-Re-Mi" illustrated in full color, the backmatter includes an author's note, extensive historical notes, and a glossary.
