Jessie Donaldson has played the flute for 26 years. One of her favorite pieces to play is “Romance No. 2” by Beethoven, a sweet and stately composition for flute, oboes, bassoons, horns, and violin. But mentally rehearsing the flute part is tricky for the occupational therapist, who lives in Auckland, New Zealand. Jessie lacks the ability to simulate sounds in her mind. When I ask her to conjure the music that she has mastered over decades, she says she can feel the fingerings she has practiced, but can’t hear the parts in her mind’s ear. In those moments, Jessie’s mind is filled with thoughts of the rhythm and structure of the music but none of the actual sounds her flute or the other instruments produce.
Going as far back as she can remember, this same silence permeates her memories, too. “I know what the sound of a laugh is,” she tells me, “but I can’t hear it in my mind. I have no memories with sounds.” Jessie only discovered that this was unusual when, by chance, she met a researcher who studies people like her.
