音乐旋律能反映地理差异，但无法预测国民幸福感或个体主义程度。
Open-Source Intelligence and Music Information Retrieval for Geographic Attribution of Musical Affect and the Ecological Limits of Population Inference
- 基于乐谱分析2393首民歌的旋律特征，用算法自动判断调式而非依赖标注数据。
- 中国民歌以大音程跳跃和高活跃度为显著特征，与其他国家差异极显著（p<10^-90）。
- 发现音乐情感地理分布与幸福指数、个体主义指数均无关联，警惕生态谬误。
人们常认为区域音乐反映民众性格，如忧郁旋律对应忧郁人群。本文检验这一直觉的可测量部分，否定其推论部分。利用埃森民歌集，从2393首去重旋律中提取2393首跨越16国7地区的符号化旋律与情感特征，使用关键音识别算法计算调式，因原数据标注不可靠。跨国家旋律结构差异巨大且高度显著：8项测试特征在各国间均达p<0.001，音程相关特征更达p<10^-90；中国民歌呈现独特的大音程跳跃与高活跃度特征（唤醒度复合指标+1.24标准差，平均绝对音程2.77半音，德国为2.17）。进一步将区域音乐情感指标与《世界幸福报告》幸福指数及霍夫斯泰德个体主义指数进行相关性分析，6项相关性均不显著（0/6）。音乐情感的地理分布真实可测，但无法预测国民幸福感或个体主义程度，任何此类推断均为生态谬误。论文发布完整提取与分析流程，并提供故障闭合校验器，可逐项复现文中所有数值。
原文摘要 · Abstract (English)
A common intuition holds that a region's music mirrors the temperament of its people, so that melancholic melodies mark melancholic populations. We test the measurable half of that intuition and reject the inferential half. Using the Essen Folksong Collection, a corpus of thousands of notated folk melodies, we extract real melodic and affect-related features from 2393 deduplicated melodies spanning 16 countries and 7 geographic regions, with the analysis performed on symbolic scores rather than audio. The mode of each melody is computed with a key-finding algorithm rather than read from the file, because the collection's own documentation warns its major and minor labels are unreliable. Cross-country differences in melodic structure are large and highly significant. All 8 tested features differ across countries at p<0.001, with the leap-related features reaching p<10^-90, and China carries a distinctive wide-leap, high-activity signature (arousal composite +1.24 standard deviations, mean absolute interval 2.77 semitones against Germany's 2.17). We then test the inferential half. We correlate the regional musical-affect measures with two published, validated national indices, the World Happiness Report ladder score and the Hofstede individualism index. None of the 6 correlations is significant (0 of 6). The geography of musical affect is real and measurable, but it does not predict how happy or how individualist a population is, and any claim that it does is an ecological fallacy. We release the full extraction and analysis pipeline, and a fail-closed checker re-derives every number in this paper from the data.
