I’m fascinated by this photo of Bonhoeffer on guitar. There’s not much said about it as far as I know. Thereagain if I read German there might be something I don’t know about. From what I gather his instrument was piano. He’s got to be playing some classical orchestral piece I imagine. But really, so little is said about his playing any stringed instruments. How does he know how? Maybe he’s just sitting and plunking around on a student’s guitar.
