[5]While the game continues to feature the use of a guitar-shaped controller to simulate the playing of rock music, Guitar Hero World Tour is the first game in the Guitar Hero series to feature drum and microphone controllers for percussion and vocal parts, similar in manner to the competing Rock Band series of games. The game allows users to create new songs through the "Music Studio" mode, which can then be uploaded and shared through a service known as "GHTunes".
The guitar interface remains relatively unchanged in World Tour. As with previous Guitar Hero titles, the guitar and bass player must hold down the correct fret button(s) on the controller while strumming in time with the notes as they scroll on-screen. One addition to the guitar gameplay is the ability to play notes while holding a sustained note. Additionally, the bass guitar player will be required to play notes representing an open E string, which is shown on-screen as a solid line across their note track. To play these notes, the bass guitar player strums the controller without pressing any fret button keys.[9] The drum interface is similar to the guitar's interface, with each on-screen note track equivalent to a colored drum head on the controller, with the bass drum indicated by a line across the note track. The drum player only needs to hit the correct drum pads simultaneously to the note gems to successfully play their track. There are also marked sections on the drum part wherein the player may play any notes they wish in a 'solo' to gain points. The vocal track requires the player to match the pitch of the notes in a manner similar to Karaoke Revolution to be successful. Special sections of each players' note track are marked with glowing notes, which, if completed successfully, builds up Star Power. Once enough Star Power is accumulated, it can be released via various means to double the band's current score multiplier. For guitar and bass, this is done by lifting the guitar controller vertically or (though not in bass) by pressing a button on the guitar face; for drums, by striking both cymbal pads on the controller at the same time; for vocals, by tapping the microphone or making a similarly quick sound.[9]
In addition to the standard four difficulty levels (Easy, Medium, Hard, and Expert) for each song and instrument, a new Beginner level has been added in World Tour.[10] This difficulty is aimed for younger and unskilled players; notes are generally simple straight lines in time with bass drum beats, and allowing any or no fret button to be held while the note is strummed (for lead and bass guitar), any drum to be hit (for drums), or any sound to be made (for vocals).[11][12]
