Abstract
A method of measuring pitch was developed by using some instruments for physical experiment and has been applied to music education to date. In the present study, the children sang the song of "Haru no Ogawa" and the pitches and intervals of the song were analyzed and discussed. The results revealed that the pitches and intervals were somewhat different with age and sex and also were influenced by the difference of melody. The study has, further, enabled us to give an immediate feedback of analytical data to music education.
