The Grooved Whale Project
Decoding Whale Song
Decoding Whale Song
The Grooved Whale Project encapsulates over 25 years of deciphering and decoding the complex vocalizations of humpback whales It serves as a unifying framework for a wide range of projects I’ve undertaken, from analyzing whale song through the lens of mathematical patterns, to composing interspecies music to interactive concerts in the wild. My work is a deeply interdisciplinary endeavor that bridges science, art, culture, and spirit. It draws from bioacoustics, information theory, and artificial intelligence extending even into SETI research as a speculative blueprint for universal language.
My research is driven by a deceptively simple question: Can whale song be considered music? This inquiry has led me into the evolutionary roots of musical structure, tracing how pattern, repetition, and symmetry—core elements of human composition—also emerge in the vocal traditions of humpback whales. integrating deep learning and musical analysis, my work focusses on exploring universal architectures and templates for communication.
At the 2024 Astrobiology Scientific Conference, I presented Song of the Curious Alien, a transdisciplinary exploration of whale song as a model for nonhuman and extraterrestrial intelligence. Cosmic pluralism meets the Drake Equation.
In Alaska with the SETI team in 2021, we engaged in a remarkable 20-minute vocal exchange with a humpback whale named Twain. As coauthor of Conversing with an Alaskan humpback whale (PeerJ 2021), I contributed to the fieldwork, analysis, and methodology, helping interpret the acoustic and emotional dynamics of the playback experiment.
Whales and Aliens is an 8-part video podcast series that explores the search for extraterrestrial intelligence (SETI) through a radically interdisciplinary lens.
Whales and Aliens is made possible with the support from TELUS STORYHIVE and will be available for free on TELUS Optic TV April 2026.
The podcast mission is to inform the search for extraterrestrial life by drawing parallels between whale societies, human civilization, and alien intelligences. Biological SETI is an emerging subfield of SETI and explores how nonhuman cognition might serve as a blueprint for detecting extraterrestrial intelligence.
The series features a wide range of disciplines and worldviews to better explore how we might understand life in the universe. Each episode features leading experts and creative thinkers who challenge how we define intelligence, communication, and the very nature of life in the Salish Sea
Since 1999, my fieldwork in Hawai‘i has centered on recording and analyzing humpback whale song from my kayak—my floating observatory. Over the years, I’ve tracked the evolving structure of whale vocalizations, monitoring changes in phrasing, motif development, and the underlying logic of their progressions.
Often battling wind, waves, and unpredictable conditions, I’ve had close encounters with whales that were both humbling and transformative. Some of the most unforgettable moments have come humpback mothers bringing their calves directly beneath me— lingering, as if offering a quiet gesture of trust.
These intimate experiences have allowed me to witness the song’s annual revolutions and subtle compressions firsthand and the interplay between the whales as they go about their daily lives, deepening my understanding of their intelligence, culture and adaptive complexity.
During my field seasons in Alaska, I’ve joined scientific expeditions focused on the rich feeding grounds where humpback whales congregate in remarkable densities. Amid the dramatic fjords and glacial waters, I’ve documented feeding calls and observed the intricate choreography of bubble-net feeding—a cooperative hunting strategy that reveals astonishing social coordination and acoustic signaling.

Despite the sheer number of whales in these northern waters, I’ve come to recognize and connect with a few individuals over time. Their unique behaviors, vocal signatures, and social roles have offered a more personal lens into the lives of these giants. These relationships, forged through repeated encounters and long hours of observation, have added emotional depth to the scientific rigor of my work, reminding me that behind every data point is a sentient being navigating a complex marine world.
Humpback whales continue to challenge and expand our understanding of non-human intelligence. Their use of tools, most notably in bubble-net feeding, is a striking example of strategic behavior and social coordination.
Beyond feeding, humpbacks exhibit complex vocal learning, long-term social bonds, and a capacity for innovation. The more time I spend with them the more I see not just instinct, but intention and intelligence.

Created with Infusion Systems I-Cube, my MIDI violin featured G-Force, Accelerometer, Touch, Turn and Proximity sensors allowing me to control sound with new gestures and explore new ways of making music.
Rather than composing a piece of music that "sounds like" whale song, I have taken a improvisational approach to let the musicians explore what it must feel like to be a singing whale. This piece can be played with any combination of 4 instruments and unfolds according to the rules of whale song.
