To make this easier, connect a regular Xbox 360 controller (i.e. the one you use to play Halo and Call of Duty games) and a microphone (an Xbox 360 headset will also work, but will require an in-game setting change to work). Play quickplay and set your difficulty to BEGINNER. Create a setlist in the order noted above. Before you start playing, turn on a fan at the highest setting and place the microphone in front of it. This is called the "fan trick" as it is NOT necessary to hit the correct pitch on beginner difficulty. As long as the microphone is picking up any kind of sound, the game will count it as "singing". It is then possible to FC (full combo) all 19 songs, continuing the phrase streak throughout each song from beginning to end. You will also unlock
Fevered Pitch in Band Hero (100% a song as a vocalist) in doing so.
NOTE: If you are playing a setlist, you will need change to the next song on the list manually by pressing
on the controller until you have finished them all.
