air's gravity is a trance-techno instrumental by Japanese composer zts (CODE ZTS LABEL), created as the original BGM for the HALFPIPE TOKYO digital attraction at SEGA's Tokyo Joypolis. It joined the maimai arcade series at the launch of maimai PLUS on December 13, 2012, and has remained a fixture in the game's catalog ever since. The track layers aggressive synthesizer leads over driving, spacey beats to evoke the sensation of floating through the air, a feeling zts has described as directly inspired by imagining how the ride would move. A pale, crystalline music video by artist Mira reinforces this weightless atmosphere with pastel visuals and drifting geometric objects. Over the game's many version updates, air's gravity's chart levels have been revised repeatedly to match rising difficulty standards. The MASTER chart (designed by 譜面-100号) is notable for containing only a single Slide note, a rarity at its level bracket, while the later Re:Master chart (designed by 某S氏) flips the philosophy entirely with 39 Slide notes and a 13+ difficulty rating. The Re:Master was added on October 23, 2020, as part of a six-song batch celebrating the maimai ALL PERFECT COLLECTION soundtrack release, marking the first new Standard charts added since the transition to the maimai でらっくす era.
