Co-produced with Dallas Taylor from the sound design podcast 20,000 Hz, the episode highlights how the TikTok sonic logo became a guerrilla branding tool and a Trojan horse—embedding itself into the ecosystem of social media platforms far beyond TikTok.

Key Discussion Points & Insights

1. Introduction: The Power of Sonic Branding (00:16–05:41)

• Opening Game: Kenny Malone and Dallas Taylor play a game sharing viral internet videos featuring unexpected voice actors. Both videos, sourced from different platforms, end with the same sound—the TikTok sonic logo—demonstrating TikTok’s brand reach.
• Setting the Scene: The episode’s premise: how TikTok’s sound, designed to travel the Internet, serves as a branding tool across platforms where its content is shared or re-posted.

Notable Quote

“The TikTok Sonic logo...the backstory to this audio logo is what today's episode is about. Because not very long ago, TikTok had an interesting problem: its users were making videos that went viral on TikTok, but also spread to Instagram and Reddit.”
— Kenny Malone (03:15)

2. What is a Sonic Logo? (05:36–07:03)

• Definition: Dallas Taylor explains the “sonic logo”—a short, memorable sound snippet tied to a brand (like McDonald’s “ba-da-ba-ba-ba”).
• Purpose: Effective sonic logos are earworms, often becoming as recognizable as visual logos.

Notable Quote

“It's super important that you're going to have a sonic logo that really can become an earworm. Easily remembered, potentially even sung or hummed.”
— Afrik Lennon (05:41)

3. The Birth of the TikTok Sonic Logo (06:42–11:41)

• Genesis: In 2020, TikTok engaged Massive Music (Afrik Lennon and Roscoe Williamson) to craft a ‘sonic identity’ to broaden TikTok’s appeal beyond Gen Z.

• Design Requirements:

  • Must not skew “too young”
  • Must express joy, safety, and welcoming
  • Must withstand heavy repetition and not annoy users
  • Should feel ‘remixable’ and open to community engagement

• Iterative Process:

  • Thousands of logo ideas
  • Early concepts focused on the literal “Tik-Tok” onomatopoeia, experimenting with everyday sounds, UGC (user-generated content), and even different instrument timbres

Notable Quotes

“We wanted to create something that could become more known, loved and embraced and even remixed by the community.”
— Afrik Lennon (08:12)

“It's gotta be in the 2000 plus.”
— Roscoe Williamson, on the number of versions created (08:26)

4. The Anatomy of TikTok’s Sound (“Boom Bling”) (11:41–15:44)

• Development: Sound refined over countless iterations; core elements:
  • Starting with a powerful 808 kick drum (emphasizing TikTok’s music roots and acting as a divider between video/music content and branding)
  • Ascending melody/chord evoking joy and “the last sunny corner of the Internet”
  • Marimba and sine wave layers for warmth and clarity
  • E major 7th chord (a richer, more emotionally nuanced sound than a simple major chord), selected over objections after consumer testing revealed it made the brand feel more mature and memorable
  • Accidental inclusion of a hyper-processed dog bark—a serendipitous sound that became integral to the final logo

Notable Quotes

“We have the tick, the first beat, which is this iconic sub bass sound, which for us is a nod to the musicality of the platform.”
— Afrik Lennon (12:12)

“The TikTok sonic logo is the most rapidly recognized sonic logo of all time.”
— Roscoe Williamson (22:26)

“That is a mistake. That is something that we left in by accident...when we took it out, the logo just didn’t have the character.”
— Roscoe Williamson, about the dog bark (16:18)

5. The Trojan Horse Marketing Strategy (17:05–20:29)

• Secret Seeding: Prior to the official launch, Massive Music and TikTok covertly released “sonic stickers”—short sound bites derived from the new logo—under the alias Sonic Collective. Creators organically picked up these sounds, unknowingly embedding TikTok’s new identity in their content.
• Outcome: By the time the sonic logo officially launched, it was already familiar on the platform, making the brand’s transition seamless and sticky.

Notable Quotes

“We launched them under an alias, which was Sonic Collective...kind of like Incognito.”
— Afrik Lennon (19:36)

“In other words, they used these stickers as kind of a Trojan horse to introduce people to these new branded sounds.”
— Dallas Taylor (19:40)

6. Viral Branding: Sonic Logo as Internet Watermark (20:38–22:37)

• Watermarking Content: Whenever TikTok users download or repost videos, TikTok attaches its sonic logo at the end—effectively branding content across Instagram, Reddit, YouTube, etc., serving as a sonic “watermark.”
• Immediate Results: Within just 3 months, research showed over 50% of people could recognize TikTok’s logo sound unaided—an unprecedented rate for a sonic brand.

Notable Quotes

“When I hear the boom bling on another app, I feel like I'm consuming TikTok content. It's almost like TikTok embedded a mini version of their app inside their competitors.”
— Dallas Taylor (21:18)

“Over 50%—so one in two—were able to recognize the sound...pretty astronomical for a new sound logo.”
— Afrik Lennon (22:06)

7. Reflections: Sonic Branding as Science & Art (22:52–23:26)

• Blending Disciplines: Both Roscoe and Afrik reveal backgrounds in science (chemistry & neuroscience of music) and the arts—underscoring that effective sonic branding is a careful mix of psychology, musicality, and marketing.

Notable Quotes

“Sonic branding, it really is that blend of science and art that excites me and gets me up in the morning.”
— Afrik Lennon (23:03)

8. Coda: The Competition Catches On (23:30–24:29)

• Instagram Copies the Move: Kenny Malone notes that Instagram, two years later, quietly introduced its own sonic logo attached to downloaded Reels—a testament to TikTok’s innovation in sound branding.
