* = personal favorite piece, ~30
(?) = likely to be true and based off of something, but not more than 90% confident, this is often used for dates such as for arrangements, very old pieces, or when the date is based off a world premiere and not explicitly stated by the composer. For grade, this signifies that there is no given grade and the piece isn't very clear on difficulty just by listening. Segments left blank are not found or completely unknown, if there is no recording for a piece, I will attempt to put some form of confirmation of the piece's existence within the notes section. More info including difficulty ratings can be found in About.
The personal list is a hand-curated collection of my personal favorite 375+ pieces that contains more in-depth research and subsequently "more accurate" difficulty ratings.
