Air Guitar is an emote unlocked after purchasing the music cape from Olaf the Bard. Upon use, the player rocks out on an air guitar. To purchase the music cape—and subsequently unlock the emote—players are required to unlock all non-holiday music tracks in the Old School RuneScape Music Player. The player will lose access to this emote if a non-holiday song is added to the game. Once all new, non-holiday songs are unlocked by the player, the emote will be accessible once again.
- The emote was previously named "Music Cape" before being changed to "Air Guitar" in a hidden update sometime in November 2015 (with the change being officially announced in an update on 10 March 2016). The update also made the emote smoother and added a sound effect that can be heard if the Music Volume in the Audio Options is enabled.
Plays when the emote is performed.
