研究通过埃森民歌集提取多国旋律特征，发现旋律结构跨国差异显著，但音乐情感地理特征与国家幸福、个人主义指数无显著关联，表明其虽真实可测却无法推断群体特性，还发布了提取分析流程及故障安全检查器。

一种普遍的直觉认为，一个地区的音乐反映了其人民的气质，忧郁的旋律标志着忧郁的人群。我们对这一直觉的可测量部分进行了测试，并否定了其推断部分。使用埃森民歌集（一个包含数千首有谱民歌的语料库），我们从跨越16个国家和7个地理区域的2393首去重旋律中提取了真实的旋律和情感相关特征，分析是基于符号乐谱而非音频进行的。每个旋律的调式是用调式查找算法计算得出而非从文件中读取，因为该集自身文档警告其大小调标签不可靠。旋律结构的跨国差异很大且非常显著。所有8个测试特征在各国间差异均达到p<0.001，与跳跃相关的特征p值达到p<10^-90，中国有着独特的大跨度跳跃、高活跃度特征（唤醒合成比德国高1.24个标准差，平均绝对音程为2.77半音，德国为2.17）。然后我们测试推断部分。我们将区域音乐情感度量与两个已发表并经验证的国家指数（世界幸福报告阶梯得分和霍夫斯泰德个人主义指数）进行关联。6个关联均不显著（6个中有0个显著）。音乐情感的地理特征是真实且可测量的，但它无法预测一个群体有多幸福或多个人主义，任何声称它能预测的说法都是生态谬误。我们发布了完整的提取和分析流程，并且一个故障安全检查器能从数据中重新得出本文中的每个数字。
英文摘要
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.
