TikTok’s sonic logo is one of the fastest growing sonic logos in history. Today, that little sound is being heard millions of times a day on apps like Instagram, Reddit and Youtube… but creating it wasn’t easy. To make it, the creative team went through thousands of iterations, executed a covert marketing strategy, and fought through a final debate about a single note. Featuring Roscoe Williamson and Aifric Lennon from MassiveMusic.

Sperm whales are fascinating creatures. Endangered and still recovering from being hunted by whalers in the 19th century, sperm whales were long targets for their spermaceti, which, according to NOAA, is “an oil sac that helps the whales focus sound.” While this oil was a commercial product to humans, to the whales, it assists communication among pods of whales that live in different regions. By studying about 60 whales in the Eastern Caribbean clan, researchers have announced in a new study that sperm whales use a complex system of clicks or coda which overlap, rise, fall, and more in a phonetic alphabet of sorts, possibly on par with the complexity of human language.
Sperm whales communicate for feeding, breeding, and other social needs. To do so, they vocalize a series of clicking noises that pass as sound through the water. A combination of clicks is a coda, but these codas seem to function like an alphabet of sounds that can be altered and combined.
“Investigating a dataset collected across over a decade of nearly 9,000 codas from the sperm whale families of the Eastern Caribbean clan, our results show that these whales have a more complex combinatorial communication system that demonstrates rubato and ornamentation, in which whales make sub-second adjustments to match one another as they converse and add extra clicks to known coda types depending on the context within their conversations,” shares Dr. Shane Gero, of Project CETI and the Dominica Sperm Whale Project.
The whales alter their coda by adding or subtracting clicks (ornamentation), drawing out the spacing (rubato), or responding in the moment to another’s “speech.” The layering and social responses may be indicative of meaning, but so far, the researchers have just classified the sounds to survey the base of the “language” they will then seek to decode. Future investigation will also be needed to compare coda across clans, as geographically specific groups can have their own dialects. […]
