It’s not the first time Mr. Einaudi’s gorgeous piano tunes have been played on the harp but this is the first time I moved one of his songs from horizontal keys to vertical strings. “Nuvole Bianche” strikes me as poignant and contemplative, a song that isn’t played so much for the glitz and glamor like a hot set of reels on the fiddle as it is for reflection and thoughtfulness. (Okay, it does get a little fancy a few minutes in…)
