SingStar games require players to sing along with music in order to score points. Players interface with their console via SingStar microphones while a music video plays in the background. The pitch players are required to sing is displayed as horizontal grey bars, which function similar to a musical stave, with corresponding lyrics displayed at the bottom of the screen. The game analyses a player's pitch and timing which is compared to the original track, with players scoring points based on how accurate their singing is. Different modes of SingStar may vary this basic pattern, but the principle is similar throughout.
SingStar includes a variety of game modes. The standard singing mode allows one or two people to sing simultaneously, either competitively or in a duet. The game also offers a "Pass the Mic" mode, which allows up to eight people to play a series of rounds in two teams.
