Rock Band is a series of rhythm games developed by Harmonix, principally for home video game consoles. Based on their previous development work from the Guitar Hero series, the main Rock Band games has players use game controllers modeled after musical instruments and microphones to perform the lead guitar, bass guitar, keyboard, drums and vocal parts of numerous licensed songs across a wide range of genres though mostly focusing on rock music by matching scrolling musical notes patterns shown on screen. Certain games support the use of "Pro" instruments that require special controllers that more closely mimic the playing of real instruments, providing a higher challenge to players. Players are scored for successfully-hit notes, while may fail a song if they miss too many notes. The series has featured numerous game modes, and supports both local and online multiplayer modes where up to four players in most modes can perform together.
