No Robust Evidence for Octave Equivalence in Bengalese Finches

2026-05-24

Abstract excerpt

<p>Octave equivalence—the tendency to perceive tones separated by a 2:1 frequency ratio as perceptually similar—is a fundamental feature of human pitch perception and a key component of musical pitch organization. Evidence for octave equivalence in nonhuman animals remains limited, and previous avian studies have generally failed to find robust octave-based generalization. Here, we tested whether Bengalese finches...
