I sat reading in these chairs and felt somehow, in an abstract rather than a religious way, that suffering shapes you. Not only my own religious thought, but that of my ancestors, affected me in some way. The thing we have as Jews is that it’s a wonderfully abstract religion. Images are not allowed, so it’s welcome to abstract thought.
I wouldn’t play it in public — you need different muscles, you can’t use the upper arm, just the fingers. But the sound has a glow, because the strings aren’t damped, as on a piano. I wanted to visit Bach’s sound world, then apply those ideas to the piano.
