The theory of Uniform Information Density states that communication is optimal when information is presented at a moderate and uniform rate. Three predictions follow for music: (1) low-probability events should be longer in duration than high-probability events; (2) lowprobability events should be juxtaposed with high-probability events; (3) an event that is low in probability in one dimension should be high in probability in other dimensions. I present evidence supporting all three of these predictions from three diverse areas of musical practice: Renaissance counterpoint, expressive performance, and common-practice themes.

音乐中的统一信息密度

均匀信息密度理论指出,当信息以中等和均匀的速率呈现时,沟通是最佳的。对音乐的三个预测:(1)低概率事件的持续时间应该比高概率事件长;(2) 低概率事件应与高概率事件并列;(3)一个事件在一个维度上概率低的事件在其他维度上的概率应该是高的。我从三个不同的音乐实践领域提供了支持所有这三个预测的证据:文艺复兴时期的对位、表现力的表演和常见的实践主题。DOI: 10.30535/mto.25.2.5 Volume 25, Number 2, July 2019 版权所有 © 2019 Society for Music Theory
