A song with a Big Rock Ending includes free Guitar/Bass/Drums/Keys fills at the end of the song. Each note strummed, pressed, or hit builds up extra points to be added to the player's score. At the end of a Big Rock Ending, one or more last notes is required to be hit in order for the bonus points to be added to the score. If the player misses any of these notes, the extra point meter will reset to zero and no bonus points will be given.
