[Game Music] UNDERTALE’s masterpiece. A BGM that leaves a mark on the heart.

Bonetrousle

Bonetrousle

This is the background music that plays when you fight Papyrus, the younger of the skeleton brothers who appears in the story.

Its cheerful tone perfectly matches Papyrus’s somewhat goofy personality.

The rhythm is fun and it never gets old to listen to.

By the way, the title is a coined word.

sans.

sans.

As Sans’s theme song, the immensely popular “sans.” has captivated countless game fans with its laid-back, breezy sound.

Its cheerful melody evokes humorous conversations with Sans, yet within its unhurried flow, the occasional hints of melancholy suggest the unfathomable depths of his inner self.

When you learn the truth hidden behind his nonchalant demeanor, you may come to realize the preciousness of the peaceful moments when this song plays.

Snowdin Town

Snowdin Town

A heartwarming piece that evokes a peaceful scene of a snow-covered town.

This is the BGM that plays in Snowdin, the first town you visit in the game.

With bright, clear keyboard tones that feel pleasant to the ear, the track carries a hint of melancholy beneath its cheerfulness, gently resonating with the listener’s heart.

Why not listen to it when you want to linger in your game memories, or savor the quiet atmosphere of a winter night?

Hopes and Dreams

087. Hopes And Dreams (UNDERTALE Soundtrack) – Toby Fox

This is the BGM that plays during the battle with Asriel’s first form.

It starts with a beautiful, calm orchestral intro, then builds as guitar and drums come in.

Its atmosphere differs from the other battle tracks, giving a refreshing and grand impression.

A track that plays in the latter half of the game in Hotland, an industrial area covered in machinery, blending techno with chiptune.

Its inorganic, slightly mysterious melody brings back that distinctive sense of tension.

You can almost picture the searing lava in the background—touching it wouldn’t just leave you with a burn.

It’s one of UNDERTALE’s popular songs, stoking the feeling that you have to see this adventure through to the end.

It’s Raining Somewhere Else

It’s Raining Somewhere Else

A track that colors the most memorable scenes with Sans.

Its jazzy, ambient arrangement melds seamlessly with a calm melody, drawing you in for a deep listen.

It beautifully captures Sans’s hidden feelings and the depth of his bond with the player, revealing a new side to a character who’s usually playful.

Give it a listen on a rainy day when you want to get lost in thought, or when you want to spend a peaceful night.

Song That Might Play When You Fight Sans

Song That Might Play When You Fight Sans

It’s a phantom battle theme that sparks your imagination—what if you had fought that character? This track was a potential theme for the battle with Sans, but it ultimately went unused in the actual game.

Even so, it’s highly regarded by Undertale fans for its quality.

It’s a chiptune with a Super Famicom-style guitar sound that leaves a strong impression, and its driving tempo grabs listeners and never lets go.

The urgency lurking within its light, snappy rhythm vividly captures the thrill and rush of combat, making your heart race before you know it.
