About Rock Band

Rock Band is a series of rhythm games first released in 2007 and developed by Harmonix. Based on their previous development work from the Guitar Hero series, the main Rock Band games have 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 score points for hitting notes successfully, but 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.
