Two studies are reported testing the conjecture that certain musical sounds or musical works may emulate the punctuated sound (ha-ha-ha) of human laughter. In the first study, 25 participants were instructed to adjust the tempo and duty cycle (articulation) of simple tone sequences to produce the most laughter-like sound. The adjusted tempos were consistent across participants but slower than measures of actual human laughter. The adjusted duty cycles were comparable to those evident in human laughter. In the second study, comedic-related musical compositions (including humoresques, badineries , and Scherzos ) were compared with similar-tempo works by the same composers. It is shown that humoresques contain more staccato passages. However, these detached articulations are not more likely to be isochronous as might be expected if emulating human laughter. Overall, the results provide mixed evidence consistent with the idea that composers emulate laughter when composing certain kinds of humorous passages.

Humoresques幽默吗？笑声与断音之间的相似性

据报道，两项研究测试了某些音乐声音或音乐作品可能模仿人类笑声的标点声音（哈哈哈）的推测。在第一项研究中，指示25名参与者调整简单音调序列的速度和占空比（发音），以产生最像笑声的声音。调整后的节奏在参与者之间是一致的，但比实际人类笑声的测量速度慢。调整后的占空比与人类笑声中的占空比相当。在第二项研究中，将与喜剧相关的音乐作品（包括幽默风格，巴迪纳里风格和Scherzos风格）与相同作曲家的类似节奏作品进行了比较。结果表明，幽默包含更多断断续续的段落。然而，如果模仿人类的笑声，这些分离的发音不太可能是同步的。总体而言，这些结果提供了混合的证据，与作曲家在创作某些幽默段落时模仿笑声的想法一致。
