Hmm, I don't know. Can I having renewed lessons in adulthood after a long hiatus (decades, actually), play the pieces I might have played had I continued my studies over those decades? That seems very unlikely to me.However, I have found now that I'm an adult, that my goal isn't to play the most advanced pieces like a virtuoso. It is to play pieces at my level like a virtuoso. This means I'm not barreling through the piano literature to reach the most advanced pieces as quickly s possible. I'm using the relatively simple pieces I'm working on now, to play them with solid technique and as complete an understanding as I can.I would rather make a masterly grilled cheese sandwich than a half assed soufflé.
