Embodiments of the disclosure relate to assignment of fingering for performance of a musical piece. In one example, a processor of an electronic system receives a file having data relating to at least one musical piece. The processor parses the file and assigns keys to occurrences of notes within the musical piece. In certain embodiments, the key-to-note assignments are based on predetermined factors, such as common patterns of learned fingering and a user typing proficiency level, and/or predetermined assignment rules, such as physical or spatial limitations with respect to the user's fingers and the keys of the keyboard. Furthermore, embodiments of the invention allow for different keys to be assigned to different occurrences of the same note or allow for a single key to be assigned to multiple notes, such as a chord, or to different notes occurring at different points in the musical piece.
