A sopranist (also, sopranista or male soprano) is a male singer who is able to sing in the vocal tessitura of a soprano usually through the use of falsetto vocal production. This voice type is a specific kind of countertenor. In rare cases an adult man may be able to sing in the soprano range using his normal or modal voice and not falsetto due to endocrinological reasons, like Radu Marian, or as a result of a larynx that has not completely developed as in the case of Michael Maniaci.
A sopranist is able to sing in the soprano vocal range which is approximately between C4 and C6, though at times may expand somewhat higher or lower. Men of all voice types can possess the wide-ranged and effective reinforced falsetto needed to produce the contralto, mezzo-soprano and soprano vocal ranges. Some countertenors can sing up into the female vocal tessituras using the modal register (normal singing production) and need not employ any falsetto. However, this extension does not reach into the upper part of soprano range going no further than an E5 or F5. Therefore, sopranists must at some point employ falsetto to sing notes in the upper part of the soprano tessitura. The exception would be those rare singers mentioned above.
Typically, the term "soprano" refers to female singers but at times the term "male soprano" has been used by men who sing in the soprano vocal range using falsetto vocal production instead of the modal voice. This practice is most commonly found in the context of choral music in England. However, these men are more commonly referred to as countertenors or sopranists. The practice of referring to countertenors as "male sopranos" is somewhat controversial within vocal pedagogical circles as these men do not produce sound in the same physiological way that female sopranos do.Michael Maniaci and Radu Marian can refer to themselves as true male sopranos because they are able to sing in the soprano vocal range using the modal voice. Maniaci is able to do this because his larynx never fully developed as do most other men's voices during puberty.
