Monsters talking to the protagonist through New Home

Undertale is the 71st track in the UNDERTALE Soundtrack. It plays while the protagonist travels throughout New Home and learns the backstory of Asgore, Toriel, Asriel, and the fallen human. The track combines the melodies of Once Upon a Time and Memory/His Theme. Part of this track is reused, slowed down by 666%, in The Choice.

Creation and development

The original version of Undertale had a bit more somber feel and came with an entirely different guitar accompaniment. According to Toby, after hearing Redline Day, he was inspired to rework the song and write a new guitar accompaniment, which would then become the basis for Memory and His Theme.

Toby Fox cited the instrumental Pneuma from the Solanin OST and the opening of Redline Day from the 2009 film Redline as main inspirations for this track.
