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., Baroque music (or ) is a style of Western art music composed from approximately 1600 to 1750. This era followed the Renaissance music era, and was followed in turn by the Classical era. Baroque music forms a major portion of the "classical music" canon, being widely studied, performed, and listened to. Key composers of the Baroque era include Johann Sebastian Bach, Antonio Vivaldi, George Frideric Handel, Claudio Monteverdi, Domenico Scarlatti, Alessandro Scarlatti, Henry Purcell, Georg Philipp Telemann, Jean-Baptiste Lully, Jean-Philippe Rameau, Marc-Antoine Charpentier, Arcangelo Corelli, Tomaso Albinoni, François Couperin, Giuseppe Tartini, Heinrich Schütz, Giovanni Battista Pergolesi, Dieterich Buxtehude, and Johann Pachelbel., A song, most broadly, is a single (and often standalone) work of music that is typically intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers who sell their recordings or live shows to the mass market are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert or recital performances. Songs are performed live and recorded on audio or video (or in some, cases, a song may be performed live and simultaneously recorded). Songs may also appear in plays, musical theatre, stage shows of any form, and within operas., Henry Purcell (or ; c. 10 September 1659  21 November 1695) was an English composer. Although incorporating Italian and French stylistic elements into his compositions, Purcell's legacy was a uniquely English form of Baroque music. He is generally considered to be one of the greatest English composers; no other native-born English composer approached his fame until Edward Elgar, Ralph Vaughan Williams, and Benjamin Britten in the 20th century., Music notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including ancient symbols or modern musical symbols and including ancient symbols cut into stone, made in clay tablets or made using a pen on papyrus, parchment or manuscript paper; printed using a printing press (ca. 1400s), a computer printer (ca. 1980s) or other printing or modern copying technology. Types and methods of notation have varied between cultures and throughout history, and much information about ancient music notation is fragmentary. Even in the same time period, such as in the 2010s, different styles of music and different cultures use different music notation methods; for example, for professional classical music performers, sheet music using staves and note heads is the most common way of notating music, but for professional country music session musicians, the Nashville Number System is the main method., 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 composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores)., Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows: 
European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity., Edward Benjamin Britten, Baron Britten (22 November 1913  4 December 1976) was an English composer, conductor and pianist. He was a central figure of 20th-century British classical music, with a range of works including opera, other vocal music, orchestral and chamber pieces. His best-known works include the opera "Peter Grimes" (1945), the "War Requiem" (1962) and the orchestral showpiece "The Young Person's Guide to the Orchestra" (1945)., A countertenor is a type of classical male singing voice whose vocal range is equivalent to that of the female contralto or mezzo-soprano voice types. The countertenor range is generally equivalent to a contralto range, extending from around G to D or E, although a sopranist (a specific kind of countertenor) may match the soprano's range of around C to C. Countertenors often are baritones or tenors at core, but rarely use this vocal range in performance. The countertenor voice type has a lower tessitura than the contralto or mezzo-soprano., An orchestra is a large instrumental ensemble typical of classical music, which features string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments., A string quartet is a musical ensemble of four string players  two violin players, a viola player and a cellist  or a piece written to be performed by such a group. The string quartet is one of the most prominent chamber ensembles in classical music, with most major composers, from the mid to late 18th century onwards, writing string quartets., A choir (also known as a chorale or chorus) is a musical ensemble of singers. Choral music, in turn, is the music written specifically for such an ensemble to perform. Choirs may perform music from the classical music repertoire, which spans from the Medieval era to the present, and/or popular music repertoire. Most choirs are led by a conductor, who leads the performances with arm and face gestures., William Turner ( 1651/2 -- 13 January 1740 , London ) was a composer and countertenor of the Baroque era . A contemporary of John Blow and Henry Purcell , he is best remembered for his verse anthems , of which over forty survive . As a singer , he was a Gentleman of the Chapel Royal from 1669 until his death ., John Blow (baptised 23 February 1649  1 October 1708) was an English Baroque composer and organist, appointed to Westminster Abbey in 1669. His pupils included William Croft, Jeremiah Clarke and Henry Purcell. In 1685 he was named a private musician to James II. His only stage composition, "Venus and Adonis" (ca. 16801687), was thought to influence Henry Purcell's later opera "Dido and Aeneas". In 1687 he became choirmaster at St Paul's Cathedral, where many of his pieces were performed. In 1699 he was appointed to the newly created post of Composer to the Chapel Royal., Dido and Aeneas (Z. 626) is an opera in a prologue and three acts, written by the English Baroque composer Henry Purcell with a libretto by Nahum Tate. The dates of the composition and first performance of the opera are uncertain. It was composed no later than July 1688, and had been performed at Josias Priest's girls' school in London by the end of 1689. Some scholars argue for a date of composition as early as 1683. The story is based on Book IV of Virgil's "Aeneid". It recounts the love of Dido, Queen of Carthage, for the Trojan hero Aeneas, and her despair when he abandons her. A monumental work in Baroque opera, "Dido and Aeneas" is remembered as one of Purcell's foremost theatrical works. It was also Purcell's only true opera, as well as his only all-sung dramatic work. One of the earliest known English operas, it owes much to John Blow's "Venus and Adonis", both in structure and in overall effect. The influence of Cavalli's opera "Didone" is also apparent., Jeremiah Clarke (c. 1674  1 December 1707) was an English baroque composer and organist., Subject: william turner , Relation: movement, Options: (A) baroque (B) baroque music (C) classical music (D) classical period (E) pop
