London and colleagues’ “A comparison of methods for investigating the perceptual center of musical sounds” (2019) compares adjustment and tapping procedures. Adopt its task-sensitive interpretation: different procedures can yield different useful information. The study does not supply a universal offset or establish a dance measurement method.

The physical-onset approach remains sufficient when the receiving task consumes a physical start. Add a perceptual procedure when the heard or felt placement changes the decision. This costs more than reading a timestamp and addresses a different result.

Extending the producer–receiver distinction to partnered movement is a methodological synthesis. The dance case asks a concrete usability question rather than asserting that auditory P-center findings transfer unchanged. Refresh the relevant result when a new timbre, interaction or sensing arrangement changes the task.
