Donkey Kong no Ongaku Asobi

Donkey Kong no Ongaku Asobi (Donkey Kong's Music Play) is a canceled game set for release on the Nintendo Entertainment System. It would have followed Donkey Kong Jr. Math as one of the edutainment games in the early Donkey Kong series.

Donkey Kong no Ongaku Asobi starred the cast of the original Donkey Kong plus series newcomer Donkey Kong Jr. The game never surfaced, and seems to have only been announced in 1983 in a Japanese handbill as well as magazines.

Game Modes
The prototype featured two modes: Music Quiz and Donkey Band.

Music Quiz
Music Quiz would seem to involve making bassist Donkey Kong play displayed notes by hammering piano keys with Mario and Pauline. Screenshots of the prototype revealed one- and two-player variations:
 * One Player: Mario plays the notes, with Pauline and her hammer on the sidelines.
 * Two Players: Both Mario and Pauline play the notes; Mario is Player 1, while Pauline is Player 2.

Donkey Band
Donkey Band would be played as a karaoke styled game in which included the player singing into the Famicom player 2 controller microphone. Donkey Kong is on bass once more with Donkey Kong Jr. playing drums, Mario playing a grand piano and Pauline as a vocalist.
