PROBLEM: Context: A voice type is a particular human singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points ("passaggio"), such as breaks and lifts within the voice. Other considerations are physical characteristics, speech level, scientific testing, and vocal register. A singer's voice type is identified by a process known as voice classification, by which the human voice is evaluated and thereby designated into a particular voice type. The discipline of voice classification developed within European classical music and is not generally applicable to other forms of singing. Voice classification is often used within opera to associate possible roles with potential voices. Several different voice classification systems are available to identify voice types, including the German "Fach" system and the choral music system among many others; no system is universally applied or accepted., Maria Malibran ( 24 March 1808 -- 23 September 1836 ) was a Spanish mezzo - soprano who commonly sang both contralto and soprano parts , and was one of the most famous opera singers of the 19th century . Malibran was known for her stormy personality and dramatic intensity , becoming a legendary figure after her death at age 28 . Contemporary accounts of her voice describe its range , power and flexibility as extraordinary ., A soprano is a type of classical female singing voice and has the highest vocal range of all voice types. The soprano's vocal range (using scientific pitch notation) is from approximately middle C (C) = 261 Hz to "high A" (A) =880 Hz in choral music, or to "soprano C" (C, two octaves above middle C) =1046 Hz or higher in operatic music. In four-part chorale style harmony, the soprano takes the highest part, which usually encompasses the melody. 
The soprano voice type is generally divided into the coloratura, soubrette, lyric, spinto, and dramatic soprano. The lyric soprano is the most common female singing voice., Singing is the act of producing musical sounds with the voice, and augments regular speech by the use of sustained tonality, rhythm, and a variety of vocal techniques. A person who sings is called a singer or vocalist. Singers perform music (arias, recitatives, songs, etc.) that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir of singers or a band of instrumentalists. Singers may perform as soloists, or accompanied by anything from a single instrument (as in art song or some jazz styles) up to a symphony orchestra or big band. Different singing styles include art music such as opera and Chinese opera, religious music styles such as gospel, traditional music styles, world music, jazz, blues and popular music styles such as pop and rock., A contralto is a type of classical female singing voice whose vocal range is the lowest female voice type.
The contralto's vocal range is fairly rare; similar to, but different from the alto, and almost identical to that of a countertenor, typically between the F below middle C (F in scientific pitch notation) to the second F above middle C (F), although at the extremes some voices can reach the E below middle C (E) or the second B above middle C (B). The contralto voice type is generally divided into the coloratura, lyric, and dramatic contralto., Subject: maria malibran, Relation: movement, Options: (A) classical music (B) pop
