Question: What type of music did Domenico Salvatori sing that was an equivalent to that of a soprano?
Context: 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. Odontophrynus salvatori is a species of frog in the family Odontophrynidae.  It is endemic to Brazil and known from its type locality in the Chapada dos Veadeiros National Park, from the Serra dos Pirineus State Park (both in the state of Goiás), and from the Federal District.  Its natural habitat is Cerrado savanna, where it occurs on the ground near waterbodies.  The tadpoles develop in small temporary streams.  It is threatened by habitat loss caused by agricultural development and fires. Domenico Foroni (10 July 1796 - 24 March 1853) was an Italian composer, conductor, and music educator.  He was born in Valeggio sul Mincio into a family of landowners.  On 7 November 1818 he married Teresa Zovetto with whom he had five children, two of whom became famous: the operatic soprano Antonietta Foroni-Conti (1822-187?)  and the composer and conductor Jacopo Foroni (1825–1858).  In 1818 he was appointed to the dual position of director and principal conductor of the Teatro Filarmonico in Verona, a position he held for over 25 years.  He was also highly active as a teacher of singing and music composition in that city.  Among his notable pupils were Gottardo Aldighieri, Paolo Bombardi, Domenico Conti, Carlo Pedrotti, Alessandro Sala, Maria Spezia-Aldighieri, and his children.  Most of his compositional output was sacred music, the majority of which was written for services at the Verona Cathedral.  Most of his music is now lost, but copies of his "Miserere" and "Messe" still exist Domenico Salvatori (27 September 1855 – 11 December 1909) along with Alessandro Moreschi, Domenico Mustafà and Giovanni Cesari, was one of the famous castrati singers of the late 19th century. A castrato (Italian, plural: "castrati") is a type of classical male singing voice equivalent to that of a soprano, mezzo-soprano, or contralto.  The voice is produced by castration of the singer before puberty, or it occurs in one who, due to an endocrinological condition, never reaches sexual maturity. Michael Maniaci (born in 1976 May 3) is an American opera singer.  Possessing a male soprano voice, Maniaci is noted for his claim to be able to sing into the upper soprano register without using falsetto, an otherwise common phonation for men who sing in high registers, such as countertenors. Although this was possible for castrati, because of the hormonal imbalance following castration, Maniaci claims that, for some unknown reason, his larynx did not develop and lengthen completely, causing his voice not to "break" in the usual manner.  Maniaci claims that this physical particularity has given him the ability to sing in the soprano register without sounding like a typical countertenor or a female singer.  There are, however, critics who claim that Maniaci actually sings in falsetto. A spinto soprano (also lirico-spinto, spinto lyric soprano or "pushed lyric") is a type of operatic soprano voice that has the limpidity and easy high notes of a lyric soprano, yet can be "pushed" on to achieve dramatic climaxes without strain.  This type of voice may possess a somewhat darker timbre, too, than the average lyric soprano.  It generally uses "squillo" to "slice" through the sound of a full orchestra, rather than singing over the orchestra like a true dramatic soprano. Che vidi oh Ciel, che vidi is a cantata da camera written by Domenico Scarlatti for soprano, two violins, and basso continuo.  It is one of 41 cantatas Scarlatti composed for soprano voice.  The text was written by poet and librettist Pietro Metastasio.  The exact date of publication is not printed on the original score.  Because this cantata belongs to the volume "Österreichische Nationalbibliothek" (named for the library in Vienna, Austria), the cantata was likely composed between 1729 and 1757, during the composer's time in Spain. Michael C. Salvatori (born 1954) is an American composer best known for his collaboration with colleague Martin O'Donnell for the soundtracks to the "Halo" video game series.  Salvatori became acquainted with O'Donnell in college; when O'Donnell was given a job offer to score a colleague's film, Salvatori and O'Donnell formed a partnership and eventually created their own production company, TotalAudio.  Salvatori continued to manage TotalAudio and worked on his own music for clients such as Disney and Wideload Games.  He most recently co-composed the soundtrack to the 2014 video game "Destiny" and its expansions, "" (2015) and "" (2016).  He also completed the soundtrack for "Destiny 2" (2017). Domenico Allegri (c. 1585 – 5 September 1629) was an Italian composer and singer of the early Baroque Roman School.  He was the second son of the Milanese coachman Costantino Allegri, who lived in Rome with his family, and was a younger brother of the more famous Gregorio Allegri.  Costantino sent three sons, Gregorio, Domenico and Bartolomeo, to study music at San Luigi dei Francesi, under the "maestro di capella" Giovanni Bernardino Nanino, brother of Giovanni Maria Nanino.  The little boy had as schoolmate his elder brother Gregorio and then Antonio Cifra, Domenico Massenzio and Paolo Agostini.
