The relationship between musicians and their musical instruments has influenced music engagement and musical structure across societies. In this work, we study how musicians react to changes in their instrument and the associations between keys and pitches using experiments that simulate the interface of the accordion. Seventeen accordionists, pianists and guitarists took part in the study. The results show accordion players are more affected by the changes in the musical interface than non-according players, for the same tasks. These observations support the extended cognition hypothesis, which proposes that coupled processes, such as the musician-instrument chain, count as an entire cognitive process.

音乐家与其乐器之间的关系影响了整个社会的音乐参与度和音乐结构。在这项工作中，我们使用模拟手风琴界面的实验来研究音乐家如何对其乐器的变化以及琴键和音高之间的关联做出反应。十七位手风琴家、钢琴家和吉他手参加了这项研究。结果表明，对于相同的任务，手风琴演奏者比非手风琴演奏者更容易受到音乐界面变化的影响。这些观察结果支持扩展认知假说，该假说提出耦合过程，例如音乐家-乐器链，算作一个完整的认知过程。
