The present study investigates shared representations of syntactic knowledge in music and action. We examined whether expectancy violations in musical harmonic sequences are also perceived as violations of the movement sequences necessary to produce them. Pianists imitated silent videos showing one hand playing chord sequences on a muted keyboard. Results indicate that, despite the absence of auditory feedback, imitation of a chord is fastest when it is congruent with the preceding harmonic context. This suggests that the harmonic rules implied by observed actions induce expectations that influence action execution. As evidence that these predictions are derived at a high representational level, imitation was more accurate for harmonically incongruent chords than for congruent chords executed with unconventional fingering. The magnitude of the effects of context and goal prioritization increased with musical training. Thus, musical training may lead to a domain-general representation of musical grammar, i.e., to a grammar of action.
本研究探讨了音乐和动作中句法知识的共享表示。我们考察了音乐和声序列中的预期违背是否也被视为产生这些序列所需的运动序列的违背。钢琴家模仿无声视频，视频中一只手在静音键盘上演奏和弦序列。结果表明，尽管没有听觉反馈，但当模仿的和弦与前一个和声环境一致时，模仿速度最快。这表明，观察到的动作所暗示的和声规则会产生影响动作执行的预期。作为这些预测是在较高的表示水平上得出的证据，对于和声上不和谐的和弦，模仿比用非常规指法执行的和谐和弦更准确。上下文和目标优先级的影响幅度随着音乐训练的增加而增加。因此，音乐训练可能会导致音乐语法的一般领域表示，即动作语法。
