 Adherents to this view maintain that a countertenor will have unusually short vocal cords and consequently a higher speaking voice and lower range and tessitura than their falsettist counterparts, perhaps from D3 to D5.Operatic vocal classification, on the other hand, prefers the terms "countertenor" and "sopranist" to "male soprano" and "male alto," and some scholars consider the latter two terms inaccurate owing to physiological differences between male and female vocal production.The only known man who can claim to be a true male soprano by that definition is Michael Maniaci, whose modal voice falls in the soprano range, akin to a woman's, because his larynx did not develop fully in puberty.
