Donkey Kong no Ongaku Asobi

Donkey Kong no Ongaku Asobi is a canceled game set for release on the Family Computer. It would have followed  and released alongside Donkey Kong Jr. Math as one of the edutainment games based on the Famicom's launch titles.

Donkey Kong no Ongaku Asobi starred the cast of Donkey Kong and 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 game 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 Lady. Screenshots of the game revealed one- and two-player variations:
 * One Player: Mario plays the notes, with Lady and her hammer on the sidelines.
 * Two Players: Both Mario and Lady play the notes; Mario is Player 1, while Lady 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 Lady as a vocalist.
