我们认为可视化在支持音乐解释的可能优势。具体来说，我们调查
使用可视化对学生的表现进行主观判断，
参考“专家”的表现，为特定方面的音乐表演-清晰度和动态。我们
反馈有效性的评估标准基于以下方面所作判断的一致性：
参与者使用每种模态，也就是说，在确定如何以及学生音乐家匹配
参考音乐家，评估每对样本所需的时间，以及对感知效用的主观看法
of the feedback反馈.
对于清晰度，参与者分配给参考与学生的平均分数的差异
每种模式的性能在统计学上都不显著。这表明，虽然可视化
策略并没有提供任何优势，通过音频播放单独演示样本，可视化
然而，它提供了足够的信息来进行类似的评级。对于动力学，我们的六个参与者中有四个
将可视化归类为有帮助的。他们对仅视觉化和两者一起的评分的平均值
条件没有统计学差异，但与仅音频治疗有统计学差异，表明
当与音频一起呈现时，可视化的优势。此外，动态下的评级
仅视觉化条件比其他条件显著更一致。
We consider the possible advantages of visualization in supporting musical interpretation. Specifically, we investigate
the use of visualizations in making a subjective judgement of a student's performance compared to
reference "expert" performance for particular aspects of musical performance-articulation and dynamics. Our
assessment criteria for the effectiveness of the feedback are based on the consistency of judgements made by
the participants using each modality, that is to say, in determining how well the student musician matches the
reference musician, the time taken to evaluate each pair of samples, and subjective opinion of perceived utility
of the feedback.
For articulation, differences in the mean scores assigned by the participants to the reference versus the student
performance were not statistically significant for each modality. This suggests that while the visualization
strategy did not offer any advantage over presentation of the samples by audio playback alone, visualization
nevertheless provided sufficient information to make similar ratings. For dynamics, four of our six participants
categorized the visualizations as helpful. The means of their ratings for the visualization-only and both-together
conditions were not statistically different but were statistically different from the audio-only treatment, indicating
a dominance of the visualizations when presented together with audio. Moreover, the ratings of dynamics under
the visualization-only condition were significantly more consistent than the other conditions.
