Previous research suggests that musical context affects the formation of similarity relations among motivic/thematic materials during listening, and that three contextual aspects, namely contrasts in surface features and the organization and development of the musical materials, shape the listening experience of complete works. We empirically investigate the effects of these three contextual aspects on the perceived similarity of motivic variations while listening to Boulez9s Anthemes . This piece exists in two versions: 1) solo violin, and 2) violin and electronics. They contain clear categories of motivic materials, whose recognition can be studied within the natural contexts of the two versions. In Experiment 1, participants freely classified motivic variations extracted from Anthemes 1 representing different motivic categories. In Experiment 2, participants provided dissimilarity ratings for these variations. From these results, motivic models were selected for each category. In Experiment 3, musicians identified variations of the models while listening to either version of Anthemes . The results indicate that musical contexts that are more contrasting on the surface, or more predictable in terms of motivic features and organization, facilitate the identification of motivic variations, whereas the overall formal development of the musical materials and their context over time disturbs the recognition of those variations.

音乐情境对听力中音乐动机识别的影响

先前的研究表明，音乐情境会影响动机/主题材料在聆听过程中的相似关系的形成，并且三个情境方面（即表面特征的对比以及音乐材料的组织和发展）影响了整首作品的聆听体验。我们在聆听Boulez9s主题曲时，对这三个语境方面对动机差异的相似性进行了实证研究。这首作品有两个版本：1）独奏小提琴，以及2）小提琴和电子产品。它们包含明确的动机材料类别，可以在两个版本的自然语境中研究它们的识别性。在实验1中，参与者可以自由分类从代表不同动机类别的Anthemes 1中提取的动机变化。在实验2中，参与者为这些变化提供了不相似等级。从这些结果中，为每个类别选择动机模型。在实验3中，音乐家在听任一版本的Anthemes时识别出模型的变体。结果表明，在表面上更具对比性或在动机特征和组织方面更具可预测性的音乐环境有助于识别动机变化，而随着时间的流逝，音乐材料及其上下文的整体形式发展会扰乱对音乐的认识。这些变化。
