“I like to think that if I were required to spend the rest of my life on a desert island,” the legendary pianist Glenn Gould once said, “and to listen to or play the music of any one composer during all that time, that composer would almost certainly be Bach.” More than any other composer, Bach provokes these sorts of dramatically intimate gestures from other celebrated musicians. Chopin would sometimes lock himself in a room and play Bach to calm his pre-performance nerves; Robert and Clara Schumann shared a “Bach diary” during their honeymoon; Pablo Casals played Bach every single morning, as a “blessing on the house.” The list could go on, seemingly ad infinitum.
