The activity of three intrinsic laryngeal muscles in the regulation of fundamental frequency and intensity of phonation was studied electromyographically in six subjects. The regulatory mechanism of fundamental frequency and intensity differed for different registers and fundamental frequencies. In general, the contribution of the laryngeal muscles in changing these parameters was greater in chest register than in falsetto and particularly less in high falsetto. There was no essential difference in the muscular activity patterns between singing in chest register and normal speech as far as control of these two aspects of voice is concerned.
