Guitar Hero World Tour on Wii uses a dedicated guitar-shaped controller (bundled with the game). It is not compatible with other Wii games.
Hold fret buttons matching on-screen gems, strum in rhythm. Use Whammy on long notes for extra Star Power. Tilt guitar neck upward (or press Star Power button) to activate Star Power.
The controller mimics a real guitar layout, making it intuitive for beginners and deep for experts.
