I’ve been playing a Benjamin Britten Nocturne on the piano lately. At the very end, there is a long chord where you dance up the keyboard and then, at the crucial moment, you move your fingers to a B flat major chord, press the keys but so softly that they don’t sound — you simply lift the sustain pedal so that the chord quietly emanates from the vibrations within the piano. It is a lovely moment and I always lean forward to hear it better.
Yesterday I noticed that the chord was humming in a very lively way — it was pulsing. “How well I am playing this now,” I thought to myself. And then I played it again. The humming was still there. Louder than usual. Pulsing. Vibrating. Weird. Suddenly I realized that the piano and my dishwasher were in sync with each other. The vibrations of the dishwasher were manifesting in the B flat major chord within the body of my piano!
Now that’s mysterious.
