The Newberry—you may be surprised to learn—has a remarkable collection of musical scores and ephemera. Above, you’ll find three of our most lauded treasures: a handwritten aria by a nine-year-old Mozart (check out that penmanship!); a first edition of Jacopo Peri’s Euridice, considered to be the first extant opera score; and Scott Joplin’s Euphonic Sounds, which brought ragtime into the respectable mainstream.

If these musical curios tickle your fancy, be sure to check out this year’s Renaissance Center NEH Summer Institute, “Music and Travel in Europe and the Americas, 1500 – 1800.” The institute, geared toward college and university professors, runs from July 15 to August 9 and includes a $3,300 stipend.
