A physiological experiment was carried out on six types of“placing the tone”by F. Husler (type No. 1 was abridged) with a forty-one years old tenor. The vowel used was“a”, and the vocal pitch was“f”in No. 2, 3a, 3b and“a'”in No. 4, 5, 6.The following items were analysed:1) The vibration mode of the vocal cords (Fig. 1) and its opening and closing time rate (Tab. 1) as observed by ultra-high speed laryngocinematography.2) The displacements of the larynx (Fig. 2, 3) and the diaphragm (Fig. 6) by X-ray cinematography.3) The sound spectrum of the voice (Fig. 4) .4) The air flow rate, the vocal intensity, the circumference of the chest and the abdomenn on four points were recorded polygraphically (Fig. 5) and mean values were estimated (Tab. 2) .The subject showed some difficulty in performing proper control of breathing for the type six.
