Reusing many gameplay elements from the Guitar Hero series, Rock Band players use peripherals modeled after musical instruments to simulate the performance of rock music. Players use these instruments by playing scrolling musical "notes" on-screen in time with the music. Rock Band expands upon the Guitar Hero series, in that it offers gameplay for drums and vocals, in addition to lead and bass guitar.
Rock Band's gameplay and on-screen interface uses a combination of elements from Guitar Hero and Karaoke Revolution.[11] Rock Band has up to three tracks of vertically scrolling colored music notes, one section each for lead guitar, drums, and bass.[11] The colored notes on-screen correspond to buttons on the guitar and drum peripherals.[11] For lead and bass guitar, players play their notes by holding down colored fret buttons on the guitar peripheral and pushing the controller's strum bar; for drums, players must strike the matching colored drumhead, or step on the pedal to simulate playing bass drum notes. Along the top of the screen is the vocals display, which scrolls horizontally, similar to Karaoke Revolution. The lyrics display beneath green bars, which represent the pitch of the individual vocal elements.[11] When singing vocals, the player must sing in relative pitch to the original vocals. A pitch indicator displays the singer's accuracy relative to the original pitch. The remainder of the screen is used to display the band's virtual characters as they perform in concert.
