Ignis Danse is a high-energy instrumental crossover track by Yuji Masubuchi, contributed from Bandai Namco's Taiko no Tatsujin (太鼓の達人) series to maimai ORANGE as part of the first Tenkaichi otogesai (天下一音ゲ祭) event, a landmark cross-company rhythm game tournament that synchronized song releases across multiple arcade titles. It launched simultaneously on November 26, 2014, in maimai ORANGE, KONAMI's jubeat saucer fulfill, Taiko no Tatsujin Kimidori Ver., and TAITO's Groove Coaster EX. Masubuchi, a veteran composer and sound director at Bandai Namco Studios, wrote the piece around a fire motif to represent the Taiko no Tatsujin entry in the event's four-elements theme. He drew inspiration from the traditional Japanese dondo-yaki fire festival and, by his own admission, the orange color of his company's logo. The track's blistering 246 BPM emerged organically during production, Masubuchi kept tapping the tempo-up button in his sequencer until the speed ran away from him, settling at its final breakneck pace. He described the result as a "high-speed boogie" (高速ブギ), a driving shuffle that doubles as a demanding boss chart in the maimai ORANGE lineup. Ignis Danse is purely instrumental with no lyrics. Its jacket features Arashi, a character from the Taiko no Tatsujin series. The song's in-game genre classification has shifted over successive maimai versions, debuting under COLLABO before moving to GAME & VARIETY (ゲーム＆バラエティ) and briefly to VARIETY in early DX releases, reflecting its cross-franchise origin. Both the Expert and Master standard charts were designed by はっぴー (Happy), with the Master chart holding a 14.5 difficulty constant and 999 total notes, featuring a dense slide-note layout that demands rapid coordinated hand movement.
