Tim Burton and Danny Elfman are basically the cinematic equivalent of peanut butter and chocolate, but when they tackled the Charlie and the Chocolate Factory soundtrack in 2005, things got messy. In a good way. Most people walk away humming the Oompa-Loompa songs thinking they're just catchy little ditties for kids. They aren't. They’re actually a dense, chaotic, and incredibly sophisticated tribute to roughly four decades of pop music history.
Honestly, it’s a miracle the score works at all.
Danny Elfman didn’t just write some background music; he provided the singing voice for every single Oompa-Loompa in the film. Thousands of them. He layered his own vocals over and over, pitching them up and down to create a "wall of sound" that feels both claustrophobic and exhilarating. If you listen closely to the "Augustus Gloop" track, you aren't hearing a choir. You're hearing one guy in a studio having a very productive breakdown.
The Secret Genre-Hopping of the Oompa-Loompa Songs
Roald Dahl’s original book provided the lyrics, but Elfman provided the soul—or rather, the several souls—of the music. Each child's "exit song" represents a specific era of music that mirrors their specific brand of bratty behavior.
Take Augustus Gloop. It’s pure Bollywood. It’s brassy, over-the-top, and utilizes heavy percussion to mimic the industrial churning of the chocolate river. Then you jump to Violet Beauregarde, which is a sharp 180-degree turn into 1970s funk and disco. It’s got that Sly and the Family Stone vibe. It's groovy, but the lyrics are literally about a girl turning into a giant berry and being juiced. The juxtaposition is jarring. That’s the point.
Veruca Salt gets the "Summer of Love" treatment. It’s psychedelic pop, reminiscent of The Mamas & the Papas or early Bee Gees. It sounds sweet and airy, masking the absolute bratty entitlement of the character. Finally, Mike Teavee is a frenetic blast of 1980s hair metal and synth-rock. It’s loud. It’s obnoxious. It perfectly captures the sensory overload of a kid raised by a television screen.

Most film scores stick to a "leitmotif"—a recurring theme for a character. Elfman threw that out the window here. Instead, he used the Charlie and the Chocolate Factory soundtrack to build a musical museum where every room has a different architect.
The Wonka Welcome Song: A Masterclass in Creepiness
We have to talk about the "Wonka's Welcome Song." You know the one. The little wooden puppets that eventually catch fire?
It’s intentionally annoying. It’s designed to sound like a theme park attraction that’s been running for twenty years too long without maintenance. The song is sickly sweet, written in a high register that grates on the nerves. When the machinery malfunctions and the puppets start melting while the music warps and slows down, it sets the tone for the entire film. This isn't the 1971 Gene Wilder version. This isn't "Pure Imagination." This is a movie about a man who hasn't had a social interaction in two decades and thinks a burning puppet show is a great greeting.
The orchestral score underneath these vocal tracks is classic Elfman—heavy on the woodwinds, frantic strings, and a certain "twinkle" that feels magical but slightly dangerous.
How it Differs from the 1971 Classic
Comparison is inevitable. The 1971 Willy Wonka & the Chocolate Factory gave us "The Candy Man" and "Pure Imagination," written by Leslie Bricusse and Anthony Newley. Those songs are legendary. They are warm. They are the musical equivalent of a hug.

The 2005 Charlie and the Chocolate Factory soundtrack is the musical equivalent of a panic attack in a neon-lit candy store.
Burton and Elfman weren't trying to out-pretty the original. They went back to the source material. Roald Dahl was a bit of a dark guy. His books have a mean streak. Elfman’s score leans into that "moralizing" tone of the original poems. In the 1971 version, the Oompa-Loompas felt like a Greek chorus giving gentle advice. In the 2005 version, they feel like a rock band mocking a child’s demise.
The Technical Wizardry Behind the Vocals
Recording the vocals for this project was a logistical nightmare. Since Elfman insisted on doing all the voices himself to maintain a specific "otherworldly" quality, the mixing process was incredibly dense.
- Vocal Layering: Elfman recorded dozens of takes for each line, changing his inflection and distance from the microphone.
- Pitch Shifting: Some tracks were digitally altered to sound more "munchkin-like," but the core energy came from his actual performance.
- Rhythmic Precision: Because the songs are so fast—especially "Mike Teavee"—the syncopation had to be perfect to match the CGI Oompa-Loompas (all played by Deep Roy).
Deep Roy actually had to take dance lessons for every single musical style. He had to learn how to move like a disco king, a Bollywood star, and a rock god. Even though he's one man, the digital duplication combined with the layered Charlie and the Chocolate Factory soundtrack makes the factory feel populated by a hive-mind of musical geniuses.
Why the Main Theme Matters
Aside from the songs, the "Main Titles" theme is one of Elfman's most underrated pieces of work. It starts with a driving, mechanical rhythm. It sounds like a factory coming to life. There’s a sense of mystery and clockwork precision. It doesn’t tell you "everything is going to be okay." It tells you "something is happening, and you better keep up."

The theme uses a lot of minor keys and sudden shifts in volume. It’s restless. Just like Wonka.
The Legacy of the Sound
Years later, this soundtrack holds up because it refuses to be background noise. It’s aggressive. It demands you pay attention to the lyrics. It’s also one of the last times we saw a major big-budget studio film take such a massive risk with its musical identity. Most modern blockbusters settle for "epic orchestral swells." Elfman gave us a 1960s psychedelic trip about a girl being dragged away by squirrels.
It’s weird. It’s loud. It’s slightly uncomfortable. It’s exactly what Roald Dahl would have wanted.
How to Listen Like an Expert
If you want to actually appreciate the complexity here, stop listening to it through your phone speakers.
- Find the Instrumental Versions: Listen to the backing tracks of the Oompa-Loompa songs. The level of detail in the "Violet Beauregarde" funk bassline is insane.
- Focus on the Percussion: In "Augustus Gloop," the drums aren't just keeping time; they are mimicking the sound of heavy machinery and splashing water.
- Contrast the End Credits: The "Main Titles" and "End Credits" bookend the film with a more traditional orchestral sweep that grounds the craziness of the middle section.
The Charlie and the Chocolate Factory soundtrack isn't just a collection of songs for a movie. It’s a specialized tribute to the history of recorded music, filtered through the brain of a man who spent his early career in a theatrical new-wave band (Oingo Boingo). It’s messy, brilliant, and worth a second listen with better headphones.
Actionable Insight:
To truly understand the depth of the 2005 score, create a playlist that alternates between the 1971 soundtrack and the 2005 version. Note the shift from melodic storytelling to rhythmic, genre-based satire. Pay specific attention to the "Mike Teavee" track; it’s widely considered by musicologists to be one of the most complex "pop" parodies ever put to film because of its rapid-fire tempo and shifting time signatures.
