This game is hilarious! I am writing this review after two hours of playing for the first time. (1) In the "conductor" mode, you're expected to waive the baton to conduct an orchestra. The music seems simple, Twinkle Twinkle Little Star, but it was arranged beautifully. The woodwind begins quietly then strings take over. Keep on waiving your baton, or if you stop, the musicians give you a strange look. The tune continues with brass, rapid string counter melody, and ends with alternating timpani and a cymbal blast. The second orchestra piece is Carmen, which can be played fast-slow-fast with a dramatic ending. (2) In the jam session, you choose the musical instrument, song, style (pop, calypso, March, Hawaiian, etc) and whether you want to be the melody, bass, harmony, or percussions. There are numerous instruments to select but there four basic ways to control or "play" them: piano control, guitar control, violin control and trumpet control. (3) In the improvisation mode, you just pick the instrument and start playing. The computer will help you with the accompaniments such as bass and drums. The melody seems to be random notes matching simple chord progressions in minor or major key. To make more fun, certain buttons add more functionality to the game depending on the musical instruments. For example, when you play guitar, use button C to play a chord, instead of a single note. When playing recorder, press B to make a trill (trill is a technique to produce two quick repeated notes). (4) The video mode enables you to record your performance and share it with your Wii friends. The game comes with four prerecorded video clips from the factory. (5) Pitch Perfect is a fun game to test your hearing and pitch recognition. For example, you are asked to arrange the Miis playing low note to high note, or you have to select two Miis playing a harmony among three Miis on the screen.
Conclusion: unlike other game which emphasizes pressing color coded buttons, this game is more on the musical side. The song selections are mostly public domain music and not as many as Guitar Hero because it is not necessary to have hundred of music library to enjoy music. A simple repertoire like Twinkle Twinkle Little Star can be arranged in limitless ways as long as you're creative. Even Mozart created a variation of this popular French tune.
