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. 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". 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. Throughout its development, pop music has absorbed influences from most other genres of popular music. 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. 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. 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. 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 musicians combined an emphasis on skill and technique with the romantic concept of art as artistic expression, original and sincere".[20] In the new millennium the term rock has sometimes been used as a blanket term including forms such as pop music, reggae music, soul music, and even hip hop, with which it has been influenced but often contrasted through much of its history.. 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. 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. In the 1940s improved microphone design allowed a more intimate singing style[19] and ten or twenty years later inexpensive and more durable 45 r.p.m. The dominance of rock by white, male musicians has been seen as one of the key factors shaping the themes explored in rock music. 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. 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.

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. 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. From the 1990s alternative rock began to dominate rock music and break through into the mainstream in the form of grunge, Britpop, and indie rock. By the late 1960s, referred to as the "golden age"[3] or "classic rock"[1] period, a number of distinct rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, raga rock, and jazz-rock fusion, many of which contributed to the development of psychedelic rock, which was influenced by the countercultural psychedelic scene. 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. Pop music (a term that originally derives from an abbreviation of "popular") is a genre of popular music, which originated in its modern form in the Western world during the 1950s and 1960s, deriving from rock and roll. From the 1990s alternative rock began to dominate rock music and break through into the mainstream in the form of grunge, Britpop, and indie rock. 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. Pop is not a do-it-yourself music but is professionally produced and packaged". Similarly, 1970s punk culture spawned the visually distinctive goth and emo subcultures. 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. and, in musical terms, it is essentially conservative". 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. 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. 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.
