Ikinari Musician is a unique rhythm game for the NES, released in Japan. The premise of the game is simple: become a musician as quickly as possible.  The game features a variety of instruments and musical genres, offering a surprisingly varied gameplay experience.  While it doesn't have the complex note charts of later rhythm games, its simplicity and charming presentation provide a different kind of rhythm game experience.  Details on the development team are scarce, but its unique mechanics suggest a creative approach to adapting musical gameplay to the NES's limitations.
