Among the three primary tonal functions described in modern theory textbooks, the pre-dominant has the highest number of representative chords. We posit that one unifying feature of the pre-dominant function is its attraction to V, and the experiment reported here investigates factors that may contribute to this perception. Participants were junior/senior music majors, freshman music majors, and people from the general population recruited on Prolific.co. In each trial, four Shepard-tone sounds in the key of C were presented: 1) the tonic note, 2) one of 31 different chords, 3) the dominant triad, and 4) the tonic note. Participants rated the strength of attraction between the second and third chords. Across all individuals, diatonic and chromatic pre-dominant chords were rated significantly higher than non-pre-dominant chords and bridge chords. Further, music theory training moderated this relationship, with individuals with more theory training rating pre-dominant chords as being more attracted to the dominant. A final data analysis modeled the role of empirical features of the chords preceding the V chord, finding that chords with roots moving to V down by fifth, chords with less acoustical roughness, and chords with more semitones adjacent to V were all significant predictors of attraction ratings.

前属和弦的知觉吸引力

在现代理论教科书中描述的三个主要音调功能中，主导和弦的代表和弦数量最多。我们假设主要功能的一个统一特征是它对 V 的吸引力，这里报告的实验调查了可能有助于这种感知的因素。参与者是初级/高级音乐专业的学生、大一音乐专业的学生以及在 Prolific.co 上招募的普通人群。在每个试验中，C 调中的四个 Shepard 音出现：1) 主音，2) 31 个不同和弦中的一个，3) 主要三和弦，以及 4) 主音。参与者评估第二和第三和弦之间的吸引力强度。在所有个体中，全音阶和半音阶主和弦的评分显着高于非主和弦和桥和弦。此外，音乐理论训练缓和了这种关系，具有更多理论训练的人认为主导和弦更容易被主导和弦所吸引。最终数据分析模拟了 V 和弦之前的和弦的经验特征的作用，发现根部向 V 下移五度的和弦、声学粗糙度较小的和弦以及与 V 相邻的半音较多的和弦都是吸引力的重要预测指标收视率。
