Training in Pitch by using Techniques of Educational Technology, I : Pitch of Sounds Produced by a Recorder and by Vocalization

Abstract

Training in pitch occupies an important part in music education. In class, however, identification of a pitch depends on the teacher's acoustic sense. An apparatus that enables the children to judge a pitch objectively with their sense of sight will be helpful in the training in pitch. The present study aims at developing such an apparatus by applying some instruments used for physical experiments. This paper reports the apparatus thus developed and the results of our study of pitch differences between the reference sound and the sounds produced by recorder-playing and by vocalization.
