Training in Pitch by Using Techniques of Educational Technology, II : Pitches and intervals of Vocal Sounds on C^1 Major Scale

Abstract

The authors have attempted to apply a method of measurement used in physics to music education. The results obtained as to single tones were already reported in the previous paper. The present study aims at investigating pitches and intervals of a series of tones produced vocally by children and making the training of vocal pitch more successful. A part of pitch measuring apparatus was newly developed. In this paper, children's vocal sounds on the most fundamental scale - c^1 major - were analyzed and discussed on the basis of the twelve-equally-tempered scale. Characteristic differences with age and sex proved to exist in pitches and intervals of their vocal sounds.
