Info: At a concert of a Chopin Medal winner I attended about ten years ago, the pianist played as his encore the very easy Prelude in e minor, Opus 28 #4, something many young pianists can play. It was gorgeous! It made me realize that playing a less difficult piece allows you to concentrate on playing more beautifully, something I struggle with. So I am trying a few easier pieces, and Catherine Rollin has many beautiful but not difficult pieces to work with!
