A chord deviating from the conventions of Western tonal music elicits an early right anterior negativity (ERAN) in inferofrontal brain regions. Here, we tested whether the ERAN is modulated by expertise in more than one music culture, as typical of folk musicians. Finnish folk musicians and nonmusicians participated in electroencephalography recordings. The cadences consisted of seven chords. In incongruous cadences, the third, fifth, or seventh chord was a Neapolitan. The ERAN to the Neapolitans was enhanced in folk musicians compared to nonmusicians. Folk musicians showed an enhanced P3a for the ending Neapolitan. The Neapolitan at the fifth position was perceived differently and elicited a late enhanced ERAN in folk musicians. Hence, expertise in more than one music culture seems to modify chord processing by enhancing the ERAN to ambivalent chords and the P3a to incongruous chords, and by altering their perceptual attributes.
偏离西方调性音乐常规的和弦会在额前区域引发早期右前负向偏移（ERAN）。在这里，我们测试了 ERAN 是否会受到一种以上音乐文化的专业知识的影响，这在民间音乐家中很常见。芬兰民间音乐家和非音乐家参与了脑电图记录。终止式由七个和弦组成。在不和谐的终止式中，第三、第五或第七个和弦是那不勒斯和弦。与非音乐家相比，民间音乐家对那不勒斯和弦的 ERAN 增强。民间音乐家对结束时的那不勒斯和弦表现出增强的 P3a。第五位的那不勒斯和弦被感知到不同，在民间音乐家中引起了延迟增强的 ERAN。因此，多种音乐文化的专业知识似乎通过增强对矛盾和弦的 ERAN 和对不和谐和弦的 P3a 来改变和弦处理，并通过改变它们的感知属性来实现。
