Instructions
Select the settings for the game as you normally would. This includes choosing the number of players and the player difficulty.
Confirm these settings for each player to enter the song list screen.
Select the "Options" menu from the song list screen. This menu allows you to change the overall settings during gameplay.
Scroll down until you see the "Hand Markers" option and switch the setting to "Off."
Confirm the changes and exit the menu to return to the song list.
Choose a song you would like to play. When it loads, the Hand Markers should no longer appear and you can play the game without the Wiimote and nunchuck.
