What are the controls for using a Guitar Hero guitar?

Answer 1

When you are playing a song, hold down the buttons as the colours come along the "highway", and when they reach the area, hit the strum key (on the body of the guitar) to hit the note. To activate star power, you can either press down the star power button or tilt the guitar up. When clear notes appear, it means you can press the coloured buttons as soon as the notes reach the area, or use the touch strip lower down the neck of the guitar to do the same.
