What You'll Find on This Site. This site provides free innovative learning materials and sheet music for playing the piano. It uses a colored graphic notation system (tablature) that provides a more natural, user-friendly way of finding the keys than traditional notation. The notes are placed on (tablature-like) diagrams of the keyboard  (called key diagrams and key maps) that show (visually) exactly which keys to play - and for rhythm, the notes appear on timelines that show exactly how many beats are required for playing each sound.
