I’m finding every Christoph Niemann one-screen-at-a-time pieces for the Times makes me some kind of happy. This time he is learning to playing the piano while stuck at home, and it is difficult for him. I took three piano lessons from a Groupon once and enjoyed myself but had no piano at home. Later we bought a house that contained a piano but there was not really room for the piano. My wife has a piano at her parents’ house, awaiting her someday when we have time for a piano. I look forward to retirement or the return of the experience-coupon era, whichever comes first.
