The differences in the functioning of phonatory organs define the divergent aspects between the speaking voice and the singing voice. The human voice represents the most natural and oldest sound source with which music can be reproduced. Physiologically, singing involves the ability to coordinate and control the musculature and structure of the vocal organ. Along life, the human body goes through anatomo-physiological changes, several of them due to the action of sex steroid hormones. The fluctuations of these hormones starting in puberty affect the vocal folds and the larynx. The literature suggests that hormone replacement therapy (HRT) has a beneficial effect on the larynx preveting the voice changes associated with menopause and increasing vocal longevity. The objective of the present study was to compare the vocal tessitura of menopausal female choir singers using HRT or not in order to determine whether hormone replacement interferes with this vocal parameter. The sample consisted of 38 menopausal women divided into four groups in accordance with the hormonal status. No significant difference in singing voice tessitura were detected between female choir singers taking or not HT with estradiol, tibolone and phytohormone.
