Happy Note! Notes in Space is a full-fledged arcade-type computer game that's both fun and educational. It will teach you about relative note durations (whole notes, half notes, quarter notes) even as you play and have fun. You'll be shooting at space faring notes from your very own spaceship. When you hit a whole note, it will split into 2 half notes. When you hit one of these half notes, it will split into 2 quarter notes. What then? Play the game and find out! For now, let's just say that you can gain extra lives by shooting down comets, and lose them almost as fast if a meteor collides with your spaceship. With its three levels of difficulty (Beginner, Advanced, Expert) and other options, Happy Note! Notes in Space is suitable for players of all ages.
