Rock music

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.

Musically, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar and drums. 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. 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. The dominance of rock by white, male musicians has been seen as one of the key factors shaping the themes explored in rock music. Rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity than pop music.

List of number-one Billboard Rock Songs

Hot Rock Songs is a record chart published by Billboard magazine. From its debut on June 20, 2009, through October 13, 2012, the chart ranked the airplay of songs across alternative, mainstream rock, and triple A radio stations in the United States. However, since the chart dated October 20, 2012, the Hot Rock Songs chart has followed the methodology of the Billboard Hot 100 by incorporating digital download sales, streaming data, and radio airplay of rock songs over all formats. Before that date the chart was ranked by overall audience impressions (the approximate number of audience impressions made for each play, as determined by BDS data cross-referenced with Arbitron listener information).

Since its introduction, thirty-nine singles have reached the number-one position on the Rock Songs chart. Foo Fighters and Linkin Park have been the most successful groups, with each having three singles to top the chart. Walk the Moon's "Shut Up and Dance" is the longest running number-one single, having spent a total of twenty-seven consecutive weeks atop the chart. Foo Fighters have spent the longest time atop the chart, as their three number-one singles have spent a combined thirty weeks at the summit. Out of the thirty-nine singles that hit the number-one position, ten singles spent two separate runs atop the chart. Coldplay's "A Sky Full of Stars" is the only single to have returned to the top position for three distinct runs. Thirty artists have recorded number-one singles. The first number-one single on the chart was Green Day's "Know Your Enemy", which led the chart's debut week. The most recent number-one single is Twenty One Pilots's "Stressed Out".

Music

Music is an art form and cultural activity whose medium is sound and silence. 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 with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (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."
