Rhythm is fundamental in many physical and biological systems. relevant to a broad range of phenomena across different fields, including animal bioacoustics, speech sciences, music cognition. As result, the interest developing consistent quantitative measures for cross-disciplinary rhythmic analysis growing. Two that can be directly applied any temporal structure are normalized pairwise variability index (nPVI) rhythm ratios (rk). The nPVI summarizes overall isochrony sequence, i.e., how regularly spaced sequence’s events are, as single value. Meanwhile, rk quantifies between adjacent intervals often used identifying categories. Here, we show these two fundamentally connected: summary static values sequence. This result offers deeper understanding applied. It also opens door creating novel, custom quantify patterns based on distribution compare domains. explicit connection one further step towards common toolkit research disciplines.

While rhythm can facilitate and enhance many aspects of behavior, its evolutionary trajectory in vocal communication systems remains enigmatic. We trace processes by investigating rhythmic abilities different species, but research to date has largely focused on songbirds primates. present evidence that cetaceans—whales, dolphins, porpoises—are a missing piece the puzzle for understanding why evolved systems. Cetaceans not only produce vocalizations also exhibit behaviors known or thought play role evolution features rhythm. These include learning abilities, advanced breathing control, sexually selected displays, prolonged mother–infant bonds, behavioral synchronization. The untapped comparative potential cetaceans is further enhanced high interspecific diversity, which generates natural ranges social complexity various hypotheses. show (particularly isochronous rhythm, when sounds are equally spaced time) prevalent cetacean used contexts baleen toothed whales. highlight key questions areas will rhythms across taxa. By coupling an infraorder-level taxonomic assessment production with comparisons other we illustrate how broadly contribute more nuanced prevalence, evolution, possible functions animal communication.
