我们就在这里谈谈旋律，谈谈音高。
这里没有音高，只有旋律。
然后把这些音符附上音高，带出这些群组，制作出顺畅的旋律。
Then give pitches to the durations so as to bring out these groupings and to make a coherent melody.
旋律与音高有关。
很不幸这种表示旋律的方法忽略了音符的时值，但这项编程任务是关于音高的，与时值无关。
It is unfortunate but true that this representation of melodies ignores the notion of musical timing; but, this programming task is about notes and not timings.
其中一个是，如果这种音高的知觉之前受到旋律的影响，即使是没有基音，辨认出这个音也有可能。
One is that if pitch perception is learned through exposure to melodies, it may be possible to recognise a tune even when the fundamental tones are absent.
在之前的研究中，志愿者分辨不出基音高于5千赫兹的旋律。
As in previous studies, the volunteers could not recognise melodies with fundamental tones above 5 kHz.
提出了一种基于相对音高和相对时延表达音乐旋律的模型，这种模型能够更好地反映不同演奏方式下的同一旋律型。
A music representation model based on relative pitch and relative time length was proposed. This model well represented the same melody under different performance conditions.
