Abstract: An electronic apparatus and method for retrieving a song, and a storage medium. The electronic apparatus includes: a storage unit which stores a plurality of songs; a user input unit which receives a hummed query which is inputted for retrieving a song; and a song retrieving unit which retrieves a song based on the hummed query from among the plurality of stored songs when the hummed query is received. The song retrieving unit extracts a pitch and a duration of the hummed query, converts each of the extracted pitch and duration into multi-level symbols, calculates a string edit distance between the hummed query and one of the plurality of songs based on the symbols, and determines a similarity between the hummed query and a song based on edit operations which are performed within the calculated string edit distance.
