Music legend Julie Andrews and daughter Emma Walton Hamilton note history of 'Do Re Mi' in new...

From “The Sound of Music” to “Mary Poppins,” Julie Andrews has earned legendary status as a musician. Now, with the help of her daughter, author Emma Walton Hamilton, Andrews has translated her musical prowess onto the page of a children’s book.

“The First Notes: The Story of Do, Re, Mi” hit the shelves Tuesday and tells the story of an 11th-century Benedictine monk named Brother Guido who invented a system of musical notation still used today. Written by Andrews and Hamilton, the book is illustrated by Chiara Fedele.

Though Andrews lost her crystal-clear soprano singing voice in 1997 after a botched throat operation, she still lends her voice to the screen — in movies like “Princess Diaries” — and the pages of more than 30 children’s books.
