音高感知是音乐旋律和言语韵律的基础。与许多动物不同，绝大多数成年人类主要以相对而非绝对音高的方式储存旋律信息，并且很容易识别出高音或低音范围内的旋律。我们发现，6个月大的婴儿也主要是相对音高处理器。熟悉旋律7天的婴儿在第八天更喜欢听与熟悉的旋律相比的新旋律，无论测试中的旋律是否以与熟悉时相同的音高呈现，还是以完美的五度（7/12个八度）或三全音（1/2个八度）上下调换。另一方面，婴儿对熟悉的旋律的转换版本没有表现出偏好，这表明他们要么不记得绝对音高，要么对他们来说它不如相对音高那么突出。(c) 2004年Elsevier B.V.出版
Pitch perception is fundamental to melody in Music and prosody in speech. Unlike many animals, the vast majority of human adults store melodic information primarily in terms of relative not absolute pitch, and readily recognize a melody whether rendered in a high or a low pitch range. We show that at 6 months infants are also primarily relative pitch processors. Infants familiarized with a melody for 7 days preferred, on the eighth day, to listen to a novel melody in comparison to the familiarized one, regardless of whether the melodies at test were presented at the same pitch as during familiarization or transposed up or down by a perfect fifth (7/12th of an octave) or a tritone (1/2 octave). On the other hand, infants showed no preference for a transposed over original-pitch version of the familiarized melody, indicating that either they did not remember the absolute pitch, or it was not as salient to them as the relative pitch.
