Story : 
A blend of two genres, Maestro! Green Groove is a unique concept combining the standards of platform games and the pleasure of music creation in an astounding way.
Discover Presto, a music-loving bird, and make him evolve in a colorful, decibel-filled journey. Use the stylus to scrape, rub, tap and whirl to the rhythm of the level’s music.
Like a good Maestro stick to the original!
Presto will jump or get off a platform in the order in which you strum the string, flying with his small wings to reach the music score.
During the game numerous challenges will require your utmost attention: special strings, flying enemies, targets to knock down as fast as lightning... all this in order to create a symphony with your fingertips. But don’t be satisfied with just a few jingles: chorus singing will earn you many more points!


Features : 
Maestro! Green Groove is one of the first games to truly make the most of the Nintendo DS microphone, allowing players to indulge themselves singing their heads off! You can let your vocal cords loose with the 4 songs featured in this game. What better way to liven up the passengers on a long trip on the underground?
Completely different than any other musical game, Maestro! Green Groove allows you to rediscover great classics such as Beethoven’s 5th Symphony or Dvorak’s Symphony “From the New World”.
Graphically the game has its own style blending 2D and true 3D graphics.
