Thanks for pointing out it's Italian. It does sound more Italian after listening to it again. The way "musica" was pronounced sounded like Spanish and I kind of focused on that word alone and thought it was Spanish
"I saw a video with David Russell and he said that a big mistake that folks make is playing pieces in a performance that are "impressive" (as in pieces that are good for exams) rather than playing pieces that are pleasing to an audience but lower in grade. He said that most folks would be better off performing pieces a few grades below where they are at.
I think it all depends on the particular audience and the purpose for performing a particular piece. Playing at a music academy for a particular specialist audience at a lunch hour concert, for instance, would obviously lend itself for more advanced pieces; than an audience at a who book you for nostalgic and other reasons, which would demand the more "popular" pieces for background or other specific reasons.
