A Central European University study published in the Proceedings of the Royal Society B found that simple vocal counting eliminates the tendency of groups to speed up together, a phenomenon called joint rushing. Researchers tested pairs tapping to a metronome and showed that a single person’s counting (with syllables placed on and between beats) stabilized group tempo. The results offer a scientific explanation for historical work songs and suggest practical applications in sports, safety and rehabilitation.
How Sea Shanties Improve Team Timing — Lab Study Shows Simple Vocal Cues Stop Groups From Speeding Up
Work songs composed to keep rhythm during labor can be found around the world.
A new lab study from cognitive scientists at Austria’s Central European University shows that simple vocal cues — such as a single person counting “one, two, one, two” — can prevent teams from unintentionally speeding up together, a common problem called joint rushing. The research, published in the Proceedings of the Royal Society B, links a centuries-old folk practice to measurable benefits for modern teamwork and coordination.
From ShantyTok To The Lab
The public revival of sea shanties on social media (often called #ShantyTok), boosted by Scottish singer Nathan Evans’ viral rendition of the New Zealand whaling shanty “Wellerman,” has renewed interest in work-song traditions. Historically, shanties were used as work songs—rhythmic calls and responses designed to synchronize repetitive, physically demanding tasks on ships, in mines, on farms and in factories.
What The Researchers Tested
Inspired by descriptions in Ted Gioia’s book Work Songs, the researchers focused on two features common to work songs: solo vocalization (a single lead voice or call-and-response) and metric subdivision (additional syllables or musical events that fill the interval between main beats). They hypothesized these elements reduce timing variability among workers and thereby limit joint rushing.
Experimental Setup
Pairs of volunteers tapped along to a metronome and then continued tapping after the metronome stopped. In the critical condition, one participant vocalized a steady count so that the spoken "one" coincided with taps and the spoken "two" occupied the interval between taps. The team compared timing variability and group tempo drift across conditions.
"Just by having one person count in a specific way, joint rushing was not only reduced but statistically eliminated," said Thomas Wolf, a co-author of the study.
Findings And Implications
The experiments produced a clear result: minimal vocal cues that align with action timing can strongly stabilize group tempo and prevent collective speeding. The authors argue that this provides empirical support for why work songs evolved and persisted across cultures.
Beyond historical interest, the findings have practical relevance. The same psychological mechanisms could inform low-cost methods to improve coordination in team sports, enhance workplace and occupational safety, support performance under stress, and assist physical rehabilitation programs that rely on rhythmic movement.
Bottom line: The folk wisdom embedded in sea shanties and other work songs has measurable power — even a simple vocal count can keep teams in sync.
