The Twenties century.

The Twenties century.

         20th-century music is defined by the sudden emergence of advanced technology for recording and distributing music as well as dramatic innovations in musical forms and styles. Because music was no longer limited to concerts, opera-houses, clubs, and domestic music-making, it became possible for music artists to quickly gain global recognition and influence.

         Twentieth-century music brought new freedom and wide experimentation with new musical styles and forms that challenged the accepted rules of music of earlier periods. Faster modes of transportation allowed musicians and fans to travel more widely to perform or listen. Amplification permitted giant concerts to be heard by those with the least expensive tickets, and the inexpensive reproduction and transmission or broadcast of music gave rich and poor alike nearly equal access to high-quality music performances.

Electronic Music.

          For centuries, instrumental music had either been created by singing, drawing a bow across or plucking taught gut or metal strings (string instruments), constricting vibrating air (woodwinds and brass) or hitting or stroking something (percussion). In the early twentieth century, devices were invented that were capable of generating sound electronically, without an initial mechanical source of vibration.

          In the 1950s the film industry also began to make extensive use of electronic soundtracks. From the late 1960s onward, much popular music was developed on synthesizers by pioneering groups like Heaven 17, The Human League, Art of Noise, and New Order.

Folk Music.

          Folk music, in the original sense of the term as coined in the 18th century by Johann Gottfried Herder, is music produced by communal composition and possessing dignity, though by the late 19th century the concept of ‘folk’ had become a synonym for ‘nation’, usually identified as peasants and rural artisans, as in the Merrie England movement and the Irish and Scottish Gaelic Revivals of the 1880s. Folk music was normally shared and performed by the entire community (not by a special class of expert or professional performers, possibly excluding the idea of amateurs), and was transmitted by word of mouth (oral tradition).

          In addition, folk music was also borrowed by composers in other genres. Some of the work of Aaron Copland clearly draws on American folk music.

Bluegrass music 

             Is a form of American roots music, and a sub-genre of country music. Bluegrass was inspired by the music of Appalachia. It has mixed roots inIrish, Scottish, Welsh, and English traditional music, and also later influenced by the music of African-Americans through incorporation of jazz elements.

Popular Music.

            Popular music, sometimes abbreviated pop music (although the term "pop" is used in some contexts as a more specific musical genre), is music belonging to any of a number of musical styles that are broadly popular or intended for mass consumption and wide commercial distribution—in other words, music that forms part of popular culture.

Blues    

        The name given to both a musical form and a music genre  that originated in African-American communities of primarily the "Deep South" of the United States around the end of the 19th century from spirituals, work songs, field hollers, shouts and chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues, and rock and roll is characterized by specific chord progressions, of which the twelve-bar blues chord progression is the most common. The blue notes that, for expressive purposes are sung or played flattened or gradually bent (minor 3rd to major 3rd) in relation to the pitch of the major scale, are also an important part of the sound.

Country music

           Is a genre of American popular music that originated in the rural regions of the Southern United States in the 1920s. It takes its roots from the southeastern genre of American folk music and Western music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars,fiddles, and harmonicas.

Disco

          Is a genre of music that peaked in popularity in the late 1970s, though it has since enjoyed brief resurgences including the present day. The term is derived from discothèque (French for "library of phonograph records", but subsequently used as proper name for nightclubs in Paris. Its initial audiences were club-goers from the African American, gay, Latino, Italian American, and psychedelic communities in New York City and Philadelphia during the late 1960s and early 1970s.

Hip hop

          Also called hip-hop, rap music, or hip-hop music, is a music genre consisting of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching, break dancing, and graffiti writing.Other elements include sampling or synthesis, and beatboxing.

Jazz

        Is a music genre that originated at the beginning of the 20th century, arguably earlier, within the African-American communities of the Southern United States. Its roots lie in the combining by African-Americans of certain European harmony and form elements, with their existing African-based music. Its African musical basis is evident in its use of blue notes, improvisation, polyrhythms, syncopation and the swung note. From its early development until the present day, jazz has also incorporated elements from popular music especially, in its early days, from American popular music.

New Age music

      Is an umbrella term for various downtempo music intended to create artistic inspiration, relaxation, and optimism. It is used by listeners for yoga,massage, meditation, and reading as a method of stress management or to create a peaceful atmosphere in their home or other environments, and is often associated with environmentalism and New Age spirituality.

Polka

       Is a Central European dance and also a genre of dance music familiar throughout Europe and the Americas. It originated in the middle of the 19th century in Bohemia. Polka is still a popular genre of folk music in many European countries and is performed by folk artists

Rock and roll

      Is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s, primarily from a combination of African-American genres such as blues, jump blues, jazz, and gospel music, together with Western swing andcountry music.Though elements of rock and roll can be heard in blues records from the 1920s and in country records of the 1930s, rock and roll did not acquire its name until the 1950s.

Alternative rock

          Is a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular by the 1990s. Most commonly associated in its heyday with a distorted guitar sound, transgressive lyrics and a nonchalant attitude, its original meaning was broader, referring to a generation of musicians unified by their collective debt to either the musical style, or simply the independent,D.I.Y. ethos of punk rock.

Progressive rock

      Is a rock music subgenre that originated in the United Kingdom, with further developments in Germany,Italy, and France, throughout the mid-to-late 1960s and 1970s. It developed from psychedelic rock and originated, similarly to art rock, as an attempt to give greater artistic weight and credibility to rock music

Punk rock

      Is a rock music genre that developed between 1974 and 1976 in the United Kingdom, United States, and Australia. Rooted in garage rock an d other forms of what is now known as protopunk music, punk rock bands eschewed perceived excesses of mainstream 1970s rock.
