"踊れオーケストラ" (Odore Orchestra, "Dance Orchestra") is an energetic Vocaloid track by Japanese composer YASUHIRO (康寛), featuring the voice of the IA vocal synthesizer. The song was added to maimai during the MURASAKi version on January 24, 2017, and is categorized under the niconico & Vocaloid genre, the in-game umbrella for user-generated Vocaloid songs originating from the Nico Nico Douga video platform. The track pairs a driving 180 BPM beat with IA's bright, agile vocal synthesis, evoking the feel of a celebratory orchestral dance number. While the wiki's dedicated song and chart commentary sections remain unpublished, the song's chart history tells a story of its own: the Master difficulty began at level 10+ at launch and was re-evaluated upward across multiple maimai version updates, eventually reaching level 12 by the FESTiVAL edition. This trajectory mirrors the broader difficulty recalibration that many MURASAKi-era charts underwent as the maimai DX series raised its ceiling for high-end play. The Expert chart was designed by Jack, and the Master chart by rioN, two notes designers whose work appears across multiple maimai versions. The official music video, featuring IA in the title card, is available on YouTube as an accompaniment to the in-game experience.
