| Research Abstract |
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.
