Affective responses to music have been shown to be influenced by the psychoacoustic features of the acoustic signal, learned associations between musical features and emotions, and familiarity with a musical system through exposure. The present article reports two experiments investigating whether short-term exposure has an effect on valence and consonance ratings of unfamiliar musical chords from the Bohlen-Pierce system, which are not based on a traditional Western musical scale. In a pre- and post-test design, exposure to positive, negative and neutral chord types was manipulated to test for an effect of exposure on liking. In this paradigm, short-term (“mere”) exposure to unfamiliar chords produced an increase only in valence ratings for negative chords. In neither experiment did it produce an increase in valence or pleasantness ratings for other chord types. Contrast effects for some chord types were found in both experiments, suggesting that a chord’s affect (i.e., affective response to the chord) might be emphasised when the chord is preceded by a stimulus with a contrasting affect. The results confirmed those of a previous study showing that psychoacoustic features play an important role in the perception of music. The findings are discussed in light of their psychological and musical implications.

已显示出对音乐的情感反应会受到声音信号的心理声学特征，音乐特征与情绪之间习得的关联以及通过曝光对音乐系统的熟悉程度的影响。本文报告了两个实验，这些实验研究短期接触是否会对Bohlen-Pierce系统中不熟悉的音乐和弦的价位和辅音等级产生影响，这不是基于传统的西方音乐等级。在测试前和测试后的设计中，对正，负和中性和弦类型的曝光进行了操作，以测试曝光对喜好的影响。在这种范例中，短期（“纯”）接触陌生的和弦只会使负和弦的配价等级增加。在这两个实验中，它都没有增加其他和弦类型的化合价或愉悦度。在两个实验中都发现了某些和弦类型的对比效果，这表明当在和弦之前施加具有对比效果的刺激时，可能会强调和弦的效果（即对和弦的情感反应）。结果证实了以前的研究结果，表明心理声学特征在音乐感知中起着重要作用。根据研究结果对他们的心理和音乐意义进行了讨论。结果证实了以前的研究结果，表明心理声学特征在音乐感知中起着重要作用。根据研究结果对他们的心理和音乐意义进行了讨论。结果证实了以前的研究结果，表明心理声学特征在音乐感知中起着重要作用。根据研究结果对他们的心理和音乐意义进行了讨论。
