Heavy metal music

Heavy metal (or simply metal) is a genre of rock music[1] that developed in the late 1960s and early 1970s, largely in the United States and the United Kingdom. Further fusion subgenres have since emerged, including pop punk, rap rock, and rap metal, as well as conscious attempts to revisit rock's history, including the garage rock/post-punk and synthpop revivals at the beginning of the new millennium. Classically, a rock band takes the form of a quartet whose members cover one or more roles, including vocalist, lead guitarist, rhythm guitarist, bass guitarist, drummer and often that of keyboard player or other instrumentalist. Further fusion subgenres have since emerged, including pop punk, rap rock, and rap metal, as well as conscious attempts to revisit rock's history, including the garage rock/post-punk and synthpop revivals at the beginning of the new millennium. New genres that emerged from this scene included progressive rock, which extended the artistic elements; glam rock, which highlighted showmanship and visual style; and the diverse and enduring subgenre of heavy metal, which emphasized volume, power, and speed. Similarly, 1970s punk culture spawned the visually distinctive goth and emo subcultures. The terms "popular music" and "pop music" are often used interchangeably, although the former is a description of music which is popular (and can include any style). According to Grove Music Online, the term "pop music" "originated in Britain in the mid-1950s as a description for rock and roll and the new youth music styles that it influenced ...".[10] The Oxford Dictionary of Music states that while pop's "earlier meaning meant concerts appealing to a wide audience ... 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.[1][2] It has its roots in 1940s' and 1950s' rock and roll, itself heavily influenced by blues, rhythm and blues and country music. The sound of rock is traditionally centered on the electric guitar, which emerged in its modern form in the 1950s with the popularization of rock and roll,[4] and was influenced by the sounds of electric blues guitarists.[5] The sound of an electric guitar in rock music is typically supported by an electric bass guitar pioneered in jazz music in the same era,[6] and percussion produced from a drum kit that combines drums and cymbals.[7] This trio of instruments has often been complemented by the inclusion of others, particularly keyboards such as the piano, Hammond organ and synthesizers.[8] The basic rock instrumentation was adapted from the basic blues band instrumentation (prominent lead guitar, second chord instrument, bass, and drums).[5] A group of musicians performing rock music is termed a rock band or rock group and typically consists of between two and five members. Such elements include generally short to medium-length songs, written in a basic format (often the verse-chorus structure), as well as the common employment of repeated choruses, melodic tunes, and hooks. Similarly, 1970s punk culture spawned the visually distinctive goth and emo subcultures. records for singles "revolutionized the manner in which pop has been disseminated" and helped to move pop music to 'a record/radio/film star system'.[19] Another technological change was the widespread availability of television in the 1950s; with televised performances, "pop stars had to have a visual presence".[19] In the 1960s, the introduction of inexpensive, portable transistor radios meant that teenagers could listen to music outside of the home.[19] Multi-track recording (from the 1960s); and digital sampling (from the 1980s) have also been utilized as methods for the creation and elaboration of pop music.[7] By the early 1980s, the promotion of pop music had been greatly affected by the rise of Music Television channels like MTV, which "favoured those artists such as Michael Jackson and Madonna who had a strong visual appeal". Harmonies range from the common triad to parallel fourths and fifths and dissonant harmonic progressions.[10] Rock songs, since the late 1950s[11] and particularly from the mid-1960s onwards, often used the verse-chorus structure derived from blues and folk music, but there has been considerable variation from this model.[12] Critics have stressed the eclecticism and stylistic diversity of rock.[13] Because of its complex history and tendency to borrow from other musical and cultural forms, it has been argued that "it is impossible to bind rock music to a rigidly delineated musical definition. Further fusion subgenres have since emerged, including pop punk, rap rock, and rap metal, as well as conscious attempts to revisit rock's history, including the garage rock/post-punk and synthpop revivals at the beginning of the new millennium.

Hip hop music

Hip hop music, also called hip-hop or rap music, is a music genre consisting of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. Pop is not a do-it-yourself music but is professionally produced and packaged". records for singles "revolutionized the manner in which pop has been disseminated" and helped to move pop music to 'a record/radio/film star system'.[19] Another technological change was the widespread availability of television in the 1950s; with televised performances, "pop stars had to have a visual presence".[19] In the 1960s, the introduction of inexpensive, portable transistor radios meant that teenagers could listen to music outside of the home.[19] Multi-track recording (from the 1960s); and digital sampling (from the 1980s) have also been utilized as methods for the creation and elaboration of pop music.[7] By the early 1980s, the promotion of pop music had been greatly affected by the rise of Music Television channels like MTV, which "favoured those artists such as Michael Jackson and Madonna who had a strong visual appeal". From about 1967 the term was increasingly used in opposition to the term rock music, a division that gave generic significance to both terms.[12] Whereas rock aspired to authenticity and an expansion of the possibilities of popular music,[12] pop was more commercial, ephemeral and accessible.[13] According to Simon Frith pop music is produced "as a matter of enterprise not art", is "designed to appeal to everyone" and "doesn't come from any particular place or mark off any particular taste". The terms "popular music" and "pop music" are often used interchangeably, although the former is a description of music which is popular (and can include any style). Early pop music drew on the sentimental ballad for its form, gained its use of vocal harmonies from gospel and soul music, instrumentation from jazz, country, and rock music, orchestration from classical music, tempo from dance music, backing from electronic music, rhythmic elements from hip-hop music, and has recently appropriated spoken passages from rap. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political in emphasis. In the second half of the 1970s, punk rock reacted against the perceived overblown, inauthentic and overly mainstream aspects of these genres to produce a stripped-down, energetic form of music valuing raw expression and often lyrically characterised by social and political critiques. Unlike many earlier styles of popular music, rock lyrics have dealt with a wide range of themes in addition to romantic love: including sex, rebellion against "The Establishment", social concerns and life styles.[10] These themes were inherited from a variety of sources, including the Tin Pan Alley pop tradition, folk music and rhythm and blues.[15] Music journalist Robert Christgau characterizes rock lyrics as a "cool medium" with simple diction and repeated refrains, and asserts that rock's primary "function" "pertains to music, or, more generally, noise."[16] The predominance of white, male and often middle class musicians in rock music has often been noted[17] and rock has been seen as an appropriation of black musical forms for a young, white and largely male audience.[18] As a result, it has been seen as articulating the concerns of this group in both style and lyrics. From about 1967 the term was increasingly used in opposition to the term rock music, a division that gave generic significance to both terms.[12] Whereas rock aspired to authenticity and an expansion of the possibilities of popular music,[12] pop was more commercial, ephemeral and accessible.[13] According to Simon Frith pop music is produced "as a matter of enterprise not art", is "designed to appeal to everyone" and "doesn't come from any particular place or mark off any particular taste". Rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity than pop music. Such elements include generally short to medium-length songs, written in a basic format (often the verse-chorus structure), as well as the common employment of repeated choruses, melodic tunes, and hooks. Throughout its development, pop music has absorbed influences from most other genres of popular music. It has also made use of technological innovation. The term "pop song" is first recorded as being used in 1926, in the sense of a piece of music "having popular appeal".[8] Hatch and Millward indicate that many events in the history of recording in the 1920s can be seen as the birth of the modern pop music industry, including in country, blues and hillbilly music.
