The ability to sing in tune is a skill acquired in high school. However, there have been cases in which students did not improve while employing the conventional practice of imitating the teacher's voice.
In this study, we conducted singing practice that used an information device that allowed high school students ― who had not made progress ― to hear the pitch quality of their own voice. Following this, we examined the efficacy of such practice.
Using the device, many of the students were able to produce pitches they could not during vocal practice with a teacher. In particular, many of the female students improved their vocalization. Many of the male students, who tended to sing in a low pitch, also saw improvement in their vocalization.
Based on the above, we concluded that it is more effective to use the information equipment (i.e., the device) with learners who have difficulty when attempting to match a teacher's voice. The reason for this is that when a student practices with her own voice, her own timbre, she is able to concentrate closely on the changes in pitch.
