Analyzing Longitudinal Data on Singing Voice Parameters of Boys and Girls Aged 8 to 12.5 and Possible Effects of a Music Pedagogical Intervention

To the best of our knowledge, for the first time this study presents longitudinal data on singing voice parameters of the voice range profile of boys and girls aged 8-12.5 years. While frequency and intensity parameters develop equally for boys and girls, the MPT is found to develop more distinctly within boys. A music pedagogical intervention of a small extent has a positive effect on the ability to sing as soft as possible.
