Gain "Star Power" by successfully hitting all of the star-shaped "Star Power" notes in a series. Your "Star Power" meter must be at least half full before you can unleash it. The meter will flash when it has reached at least half-full.
Press the "A" button on the Wii Remote to unleash "Star Power" when you are in the "Vocal" position. Alternatively, tap the top of the microphone.
Tilt the guitar control at a steep angle to unleash "Star Power" when you are playing in the "Guitar" or "Bass" positions. Alternatively, press the "Star Power Button" to activate "Star Power" with the guitar controller.
Hit the yellow and orange cymbal pads at the same time on the drum kit controller to unleash "Star Power" when you are playing in the "Drummer" position.
