One of the most indispensable elements for creating fear is the background music (BGM).
Whether it’s environmental sounds or the distorted tones of ominous strings, that kind of BGM really stirs up fear, doesn’t it?

[2026] Eerie BGM That Stokes Fear | Compilation (1–10)
Kamaitachi no Yoru – Suspicion and DoubtKatō Kōta

A track featured in the horror game Kamaitachi no Yoru.
As the title suggests, a sense of unease washes over you the more you listen.
It’s a piece from the second installment in the series that followed Otogirisō, which introduced the new “sound novel” genre on the Super Famicom.
Because the game sits halfway between watching TV and playing a game, the music deliberately sticks to what you might call a traditional score.
Persecution of the masses

Composed by Shiro Sagisu, this is the main theme used not only in the film Shin Godzilla but also in its trailers.
The title “masses” refers to the Mass, and the theme is characterized by choral elements that evoke a mass setting.
Theme of The ExorcistMike Oldfield

Many people were probably quite shocked by that sensational footage at the time.
This is the theme song from a movie made around the theme of a spirit medium and exorcist.
It’s such a well-crafted piece that you almost feel as if you might get possessed while listening to it.
The endlessly looping high-pitched refrain stirs up a sense of fear.
Hedwig’s Theme: Harry Potter and the Chamber of SecretsJohn Williams

When you think of the Harry Potter films, this is the song that surely makes everyone nod in agreement.
Composed by John Williams, this piece brims with a mysterious allure that whisks listeners into a magical world in an instant.
The melody, opening with the sparkling timbre of the celesta, is perfect for heightening Halloween’s spooky-yet-festive mood.
It first debuted on the album Harry Potter and the Sorcerer’s Stone and went on to color the story in the soundtrack for the sequel, Harry Potter and the Chamber of Secrets (released in November 2002).
Incidentally, it’s such an emblematic piece of the series that it’s even quoted in the spin-offs.
Play it on Halloween night, and you’ll feel as if you’ve stepped right into a school of witchcraft and wizardry!
Ballet Music “The Sleeping Beauty”: Puss-in-Boots and the White Cat (Act III)Pyotr Tchaikovsky

How about a comical piece to heighten Halloween’s mischievous mood? It’s a work included in the ballet suite The Sleeping Beauty by Pyotr Tchaikovsky, who created many masterpieces of ballet music.
This piece brilliantly depicts, through music, two fairy-tale cats as they frolic and hiss at each other.
With phrases that mimic meows and rhythms suggesting agile movements, it feels as if costumed characters are dancing right before your eyes—just listening is enough to lift your spirits.
The ballet containing this piece premiered in January 1890, and its extraordinary wedding-celebration setting also suits the Halloween vibe perfectly.
Play it as background music for your party, and it will help create a strange and delightful night.
