Temporal synchrony is important for music performance, and production must be aligned with auditory perception for effective synchronization to occur. Nonlinear dynamics accounts suggest that individuals synchronize most optimally at the rates that they spontaneously perform such actions, though it is unknown whether these individual rate biases influence auditory perception specifically. This online study investigated whether individual biases in the production of familiar melodies are reflected in the perception of auditory synchrony. Participants performed two tasks: (1) a singing task, to identify individuals’ spontaneous rates, and (2) a perceptual task, in which a melody was presented at different tempi (centred around the participant’s own spontaneous rate) with a metronome click superimposed at different degrees of asynchrony. Participants judged whether metronome clicks occurred earlier than, later than, or in synchrony with melody tones. A large range of individual spontaneous rates was found, although perception of synchrony was not superior at those rates. Individuals with greater musical training showed enhanced sensitivity in both discrimination of temporal order and detection of asynchrony.
