I have undertaken the process of documenting all of the sheet music for piano that I currently own. I've created lists that are sorted into levels of difficulty, which I determined based on existing rating systems including Henle Verlag, IMTA, Piano Literature for Teaching and Performance (Magrath 2021), NYSSMA, Piano Library, Piano Street, RCM, or as included in method books or graded collections. This collection is by no means complete and only reflects the music in my personal library, but I hope it can serve as a useful resource for piano students and performers.
Repertoire lists are labeled by a letter system that I created. Click on any of the links below based on your estimated playing level and search through the music. When in a repertoire list, find the style period first, then look for music that might suit you. There are no links to recordings or sheet music, though you can listen to pieces on your own that might interest you.
