拆解乐器部分，发现节奏旋律更影响听感相似性。
Investigation of perceptual music similarity focusing on each instrumental part
- 基于大规模听觉测试，分乐器分析音乐相似性
- 节奏和旋律对感知相似性影响大于音色，鼓乐例外
- 现有特征主要捕捉音色相似性，忽略其他因素
本文通过大规模听觉实验（586名受试者）研究音乐片段在不同乐器部分上的感知相似性，旨在推动基于乐器部分的音乐检索。实验使用slakh2100数据集的音频及其分轨（stems），从音色、节奏、旋律和整体四个维度评估相似性。结果表明：1）感知相似性随关注的乐器部分而异；2）除鼓乐旋律外，节奏与旋律对感知相似性的影响大于音色；3）现有音乐相似性特征主要反映音色层面的相似性，难以捕捉其他维度的感知差异。
原文摘要 · Abstract (English)
This paper presents an investigation of perceptual similarity between music tracks focusing on each individual instrumental part based on a large-scale listening test towards developing an instrumental-part-based music retrieval. In the listening test, 586 subjects evaluate the perceptual similarity of the audio tracks through an ABX test. We use the music tracks and their stems in the test set of the slakh2100 dataset. The perceptual similarity is evaluated based on four perspectives: timbre, rhythm, melody, and overall. We have analyzed the results of the listening test and have found that 1) perceptual music similarity varies depending on which instrumental part is focused on within each track; 2) rhythm and melody tend to have a larger impact on the perceptual music similarity than timbre except for the melody of drums; and 3) the previously proposed music similarity features tend to capture the perceptual similarity on timbre mainly.
