Musicians are typically identified in research papers by some single item measure (SIM) that focuses on just one component of musicality, such as expertise. Recently, musical sophistication has emerged as a more comprehensive approach by incorporating various components using multiple question items. However, the practice of SIM continues. The aim of this paper was to investigate which SIM in musical sophistication indexes best estimates musical sophistication. The Ollen Musical Sophistication Index (OMSI) and the Goldsmiths Musical Sophistication Index (Gold-MSI) were analyzed. The OMSI musician rank item (“Which title best describes you?”) was observed to be the best SIM for predicting OMSI and Gold-MSI scores. Analysis of the OMSI item indicated three parsimonious musical identity categories (MIC); namely, no musical identity (NMI), musical identity (MI), and strong musical identity (SMI). Further analyses of MIC against common SIMs used in literature showed characteristic profiles. For example, MIC membership according to years of private lessons are: NMI is 10 years. The finding of the study is that the SIM of musician rank should be used because of its face validity, correlation with musical sophistication, and plausible demarcation into the three MIC levels.

基于音乐复杂度的单项测度，用于识别音乐家和非音乐家类别

音乐家通常在研究论文中通过一些单项指标（SIM）进行识别，这些指标仅关注音乐性的一个组成部分，例如专业知识。最近，通过使用多个问题项合并各种成分，将音乐的复杂性作为一种更全面的方法出现了。但是，SIM卡的做法仍在继续。本文的目的是研究在音乐复杂度指标中哪个SIM可以最好地估计音乐的复杂度。分析了奥伦音乐复杂度指数（OMSI）和戈德史密斯音乐复杂度指数（Gold-MSI）。OMSI音乐家排名项目（“哪个标题最能描述您？”）被认为是预测OMSI和Gold-MSI分数的最佳SIM卡。对OMSI项目的分析显示了三个简约的音乐身份类别（MIC）；即没有音乐身份（NMI），音乐身份（MI）和强音乐身份（SMI）。针对文献中使用的常见SIM对MIC进行的进一步分析显示了特征曲线。例如，MIC的会员资格根据私人课程的年限为：NMI为10年。该研究的发现是，应该使用音乐家级别的SIM卡，因为它具有面部表情的有效性，与音乐技巧的相关性以及合理的划分为三个MIC级别。
