Happy Note! Play It By Ear

From Happy Note:

A real computer game (with points and lives to win and lose, a Hi-Score list etc.) that teaches you to recognize music notes by ear. Easy to customize, Happy Note! Play It By Ear lets you learn at your own pace. It requires no previous knowledge of music. Its user-friendly interface allows you to start playing and learning right away, and its "Cartoons" option makes it even more fun. You can choose between the syllabic (Do Re Mi...) and alphabetical (A B C... - or A H C for German speakers) notation systems. With a simple click, you can also decide how many lives and bonus points you'll start the game with and how many notes you'll have to hear and recognize to win. It features the same Learning menu as the game Happy Note! Treble and Bass clef. Both games are therefore fully compatible and complementary.
