Instructions
Use the "L2" and "L1" buttons to play "green" colored notes and "red" colored notes, respectively. The "L2" and "L1" buttons are the left shoulder buttons, located at the top of the DualShock controller.
Use the "R2" and "R1" buttons to play "blue" colored notes and "yellow" colored notes, respectively. The "R2" and "R1" buttons are the right shoulder buttons, located at the top of the DualShock controller.
Use the "X" button on the front of your DualShock controller to play "orange" colored notes during songs.
Use the "Select" button to use the "Start Power" that you build up during songs. This can give you a bonus, causing you to win more points than normal during gameplay.
Use the "Left" joystick on the front of your DualShock controller to act as the "whammy bar." This bar can change the pitch of notes during gameplay, which can cause you to win more points--if used correctly.
