The Star Power Meter is a meter that shows how much Star Power you earned. When you complete a Star Power Path, The Star Power is added to the meter. Once the Star Power Meter is at least half full, the player can activate Star Power by pressing the select button or momentarily tilting the guitar into a vertical position. When Star power is activated, the Star Power Meter will empty. The Star Power Wears off when the meter is completely empty. The Star Power Meter can also be filled by using the Whammy Bar during sustained notes within Star Power Segments.
