Gao and colleagues’ Shimon study compared gesture conditions while pianists followed a preprogrammed robot. Head-plus-arm gestures helped in changing-tempo conditions; the constant-tempo comparison did not show that benefit. This supports a conditional anticipatory-cue option, not a universal gesture prescription or demonstrated mutual adaptation.

Lau and colleagues’ robot ensemble integration connects mechanical realization and timing communication. Its improved end-of-piece alignment motivates testing those dependencies; it does not establish every within-phrase alignment.

Cha’s Takadimi reconsideration supplies the duration-information objection. Hoffman’s teaching recommendation supplies beat-keeping movement; Birch and Walsh’s conducting proposal offers a response to Cha. A maintained beat reference still needs separate sustain/rest information; the teaching proposals do not establish comparative superiority. The general allocation method here is a synthesis of these contributions. Reconsider a selected cue when its receiving benefit, access or competing demand changes.
