论文摘要
音乐大规模的形式是多个酒吧的音乐单元的结构，使用了25名参与者的脑电图测量，听取了一段电子舞蹈音乐（EDM）的前四分钟。针对所有电极计算的事件相关电位（ERP）的大容积显示不同大脑区域之间相位同步的动力学。在这里，感知参数的局部最大值对应于强的同步，这在时间点上达到了最终，在这些时间点上，音乐上的大规模形式边界是从感知到的。使用配对样品t检验发现了局部最大值和最小值之间的显着差异，在γ波段eeg eeg频率范围内最强烈地显示了不同大脑区域之间的整体神经同步。这种同步在音乐大规模形式的边界之前增加，然后减少，因此代表了音乐大规模的形式感知。
Music large-scale form, the structure of musical units ranging over several bars, are studied using EEG measurements of 25 participants listened to the first four minutes of a piece of electronic dance music (EDM). Grand-averages of event-related potentials (ERPs) calculated for all electrodes show dynamics in phase synchronization between different brain regions. Here local maxima of the perceptual parameters correspond to strong synchronization, which culminate at time points, where musical large-scale form boundaries were perceptually expected. Significant differences between local maxima and minima were found, using a Paired Samples t-test, showing global neural synchronization between different brain regions most strongly in the gamma-band EEG frequency range. Such synchronization increases before musical large-scale form boundaries, and decreases afterwards, therefore representing musical large-scale form perception.
