Problem:Context: The River Soar is a major tributary of the River Trent in the English East Midlands and is the principal river of Leicestershire. The source of the river is midway between Hinckley and Lutterworth. The river then flows north through Leicester, where it is joined by the Grand Union Canal. Continuing on through the Leicestershire Soar Valley, it passes Loughborough and Kegworth until it reaches the Trent at the county boundary. In the 18th century, the Soar was made navigable, initially between Loughborough and the Trent, and then through to Leicester. It was not until the early 19th century that it was linked by the Grand Union Canal to the wider network to the south and to London., Art rock is a subgenre of rock music that generally reflects a challenging or avant-garde approach to rock, or which makes use of modernist, experimental, or unconventional elements. Art rock aspires to elevate rock from teen entertainment to an artistic statement, opting for a more experimental and conceptual outlook on music. Influences may be drawn from several genres, such as experimental rock, avant-garde music, classical music, and jazz., Rock music is a genre of popular music that originated as "rock and roll" in the United States in the 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and the United States. It has its roots in 1940s' and 1950s' rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical sources., Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound.", Richard Wayne Penniman (born December 5, 1932), known as Little Richard, is an American musician, singer and songwriter., Roger Chapman ( born Roger Maxwell Chapman on 8 April 1942 in Leicester ) , also known as Chappo , is an English rock vocalist . He is best known as a member of the progressive rock band Family , which he joined along with Charlie Whitney , in 1966 and also the rock , R&B band Streetwalkers formed in 1974 . His idiosyncratic brand of showmanship when performing and vocal vibrato led him to become a cult figure on the British rock scene . Chapman is claimed to have said that he was trying to sing like both Little Richard and his idol Ray Charles . Since the early 1980s he has spent much of his time in Germany and has made occasional appearances there and elsewhere . He was awarded an Artist of the Year award in 1980 for his vocals on Mike Oldfield 's song `` Shadow on the wall '' . In 2004 he was awarded a Lifetime Achievement Award ., Progressive rock (shortened as "prog"; sometimes "art rock", "classical rock" or "symphonic rock") is a broad subgenre of rock music that developed in the United Kingdom and United States throughout the mid to late 1960s. Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening, not dancing., The East Midlands is one of nine official regions of England at the first level of NUTS for statistical purposes. The eastern part of the Midlands, it consists of Derbyshire, Leicestershire, Lincolnshire, Northamptonshire, Nottinghamshire and Rutland., 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., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Raymond Charles Robinson (September 23, 1930  June 10, 2004), known professionally as Ray Charles, was an American singer, songwriter, musician, and composer. Among friends and fellow musicians he preferred being called "Brother Ray." He was often referred to as "The Genius." Charles was blind from the age of seven., Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms"., Streetwalkers were an English rock band formed in late 1973 by two former members of Family, vocalist Roger Chapman and guitarist John "Charlie" Whitney. They were a five piece band which evolved from the Chapman, Whitney band., Leicester is a city and unitary authority area in the East Midlands of England, and the county town of Leicestershire. The city lies on the River Soar and at the edge of the National Forest., Vibrato (Italian, from past participle of "vibrare", to vibrate) is a musical effect consisting of a regular, pulsating change of pitch. It is used to add expression to vocal and instrumental music. Vibrato is typically characterised in terms of two factors: the amount of pitch variation ("extent of vibrato") and the speed with which the pitch is varied ("rate of vibrato")., Subject: roger chapman, Relation: occupation, Options: (A) band (B) composer (C) entertainment (D) guitarist (E) major (F) musician (G) official (H) opera (I) rapping (J) religious (K) singer (L) united kingdom (M) vocalist
