I feel my repertoire is just too small, and wish to add one thing new and completely different. Since all the items i can play are calm and kind of completely satisfied (Mozart’s Sonata Facile and Valse op 39 n°15 by Brahms are good examples) I wished one thing with a darker and extra unsettling feeling.
I used to be simply listening to Erlkönig by Schubert and it will be excellent, however it appears fairly troublesome. I am at a beginner-intermediate stage. Any suggestions, please?
