我们研究的目的是揭示西方音乐的等级音阶音高结构的神经相关性。记录了11名音乐家和12名非音乐家在被动和主动条件下的脑电图（EEG）。E大调音阶的所有音高都被呈现出来，第一音阶音高的出现频率高于其他音阶。在六个不常见的音阶音高，结果表明，最大的NI为第五音阶音高最高的音阶音高结构。这表明，在层次结构中，高级音高的神经表征增强了。此外，在音乐家的P3的幅度调制的音高的状态。总之，层次音调关系可以通过ERP探测到尺度的稀疏呈现的音调。
THE GOAL OF OUR STUDY WAS to reveal neural correlates of the hierarchical scale pitch structure of Western music. Electroencephalography (EEG) was recorded from 11 musicians and 12 nonmusicians in passive and active conditions. All pitches of the E major scale were presented, with the first-scale pitch having a higher frequency of occurrence than the others. Among the six infrequently presented scale pitches, results showed largest NI for the fifth-scale pitch highest in the scale pitch structure. This suggested enhanced neural representations for a pitch high in hierarchy. Moreover, in musicians the amplitude of P3 was modulated by the status of the pitch. Taken together, the hierarchical tonal relations may be probed by ERPs to sparsely presented tones of the scale.
