Artful evaluation perspectives of music representation were found out by considering the results of wave analyses for experts and beginners. The wave analyses were done from points of view of waves, sonagrams and formants.Major perspectives are as follows : 1) 'Fluctuation' exists in the time point of 0.3 seconds from the experts' vocalization, 2) Proficiency levels of learners can be judged by the states of balanced formants, 3) The experts' pitches become stable within 0.3 seconds from their vocalization, 4) The beginners take more than 0.6 seconds to stabilize their pitches, and 5) The degrees of proficiency are made out by the fact that high overtones are gradually included in the bound of sounds.Besides, lessons utilizing these results of the analyses were done in the classes of voice trainings.

通过考虑专家和初学者的波形分析结果，找到了音乐表现的巧妙评估视角。波分析从波、声谱图和共振峰的角度进行。主要观点如下：1）专家发声0.3秒时间点存在“波动”，2）可以判断学习者的熟练程度3）专家发声后0.3秒内音调稳定，4）初学者需要0.6秒以上才能稳定音调5）熟练程度是通过高泛音逐渐包含在声音范围内来确定的。此外，在语音训练课程中也进行了利用这些分析结果的课程。
