Special sections, marked by starred notes, can be used to build Star Power. A string of ten consecutive correct notes earns a multiplier to increase the player's score, which can occur up to four times. When the meter drops too low, the player fails the song, represented in-game by the band being booed off the stage. Missing a note causes the performance meter to drop. The game simulates hammer-ons and pull-offs for sections with a rapid series of notes, allowing the player to forgo strumming on specifically marked notes. Notes can be sustained, during which the fret button is held until the note is complete, and they can also form two- to four-note chords. To hit notes using the guitar controller, the player hits the strum bar while holding down the corresponding colored fret buttons. The player hits notes as they scroll down the note highway towards the bottom of the screen in time with music to maintain their performance and earn points.

Gameplay for Guitar Hero III is similar to previous titles in the series. Guitar Hero III maintains the previous modes of gameplay from the earlier games (Career Mode and Co-op career mode), and introduces Battle Model, which tweaks the Battle Power sequences of Guitar Hero II by allowing players to earn attacks through superior performance that they can use against their opponent.

Just as in previous Guitar Hero games, players control the game by using a guitar-shaped controller, and use the strum bar while holding down appropriately colored fret buttons to strike notes as they scroll to the bottom of the screen. Released in 2007 by Neversoft and Activision, Guitar Hero III: Legends of Rock brought the addictive gameplay of the original two games to a wide variety of platforms.
