摘要根据学习理论和实践观察，师生之间的交流是音乐表达有效学习的关键因素。改善这种沟通的一种可能性是在课程中引入视觉反馈（VFB）。在目前的研究中，提出了一种新型的实时VFB，它代表了一个抽象的视觉图像（大小和形状）的参数的声学参数（响度和定时）的变化。我们评估了使用VFB对模仿简单节奏模式中的时间和响度偏差的影响。我们还研究了学习的技能如何以新的节奏转移到相同的任务中，以及新的任务。24名业余音乐家参与了这项实验，其中包括模仿和感知任务。结果表明，VFB有助于提高模仿响度模式的能力，但对学习时间模式的改善没有促进作用。迁移学习效果的分析表明，学习技能模仿节奏转移时，任务是相似的：技能转移到相同的任务（模仿新的节奏），但不是新的任务（感知）。
Abstract According to learning theories and empirical observations, communication between teachers and students is a crucial factor in effective learning of musical expressions. One possibility for improving this communication could be the introduction of visual feedback (VFB) in the lesson. In the current study, a new type of real-time VFB is proposed, which represents changes in acoustical parameters (loudness and timing) as parameters of an abstract visual image (size and shape). We evaluated the effects of using VFB on imitations of timing and loudness deviations in simple rhythmic patterns. We also studied how learned skills transfer to the same task with new rhythms, as well as to new tasks. Twenty-four amateur musicians participated in the experiment that included both imitation and perception tasks. Results indicated that the VFB was helpful for improving to imitate loudness patterns, while it did not enhance improvement of learning timing patterns. Analysis of transfer of learning effects indicated that learned skills to imitate rhythms were transferred when tasks were similar: skills transferred to the same task (to imitate new rhythm) but not to new task (perception).
