Halo began as a first-person shooter series from Bungie and Microsoft, and its theme, with its wordless chant and orchestral swell, became one of gaming's most recognisable sounds after the first game arrived in 2001. Bass-boosted edits later took that familiar melody and exaggerated its low frequencies for short videos, where the overblown sound matched dramatic or ironic moments. It remains popular because the original theme already signals something epic, so the boosted version works instantly even for viewers who have never played the game.
