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. 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). Typically, rock is song-based music usually with a 4/4 time signature using a verse-chorus form, but the genre has become extremely diverse. 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. Pop music has been dominated by the American and (from the mid-1960s) British music industries, whose influence has made pop music something of an international monoculture, but most regions and countries have their own form of pop music, sometimes producing local versions of wider trends, and lending them local characteristics.[20] Some of these trends (for example Europop) have had a significant impact of the development of the genre. Punk was an influence into the 1980s on the subsequent development of other subgenres, including new wave, post-punk and eventually the alternative rock movement.

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.

Rock music has also embodied and served as the vehicle for cultural and social movements, leading to major sub-cultures including mods and rockers in the UK and the hippie counterculture that spread out from San Francisco in the US in the 1960s. in the early 1960s [the term] 'pop music' competed terminologically with Beat music [in England], while in the USA its coverage overlapped (as it still does) with that of 'rock and roll'". 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".

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. Musically, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar and drums. It is "not driven by any significant ambition except profit and commercial reward ... It has also made use of technological innovation. Rock music is traditionally built on a foundation of simple unsyncopated rhythms in a 4/4 meter, with a repetitive snare drum back beat on beats two and four.[10] Melodies are often derived from older musical modes, including the Dorian and Mixolydian, as well as major and minor modes.

Rock music has also embodied and served as the vehicle for cultural and social movements, leading to major sub-cultures including mods and rockers in the UK and the hippie counterculture that spread out from San Francisco in the US in the 1960s. 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. Rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity than pop music. 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. 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. 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. As a genre, pop music is extremely eclectic, often borrowing elements from other styles including urban, dance, rock, Latin and country; nonetheless, there are core elements which define pop.
