what's the difference between punk rock and rock
Punk rock Punk rock (or "punk") is a rock music genre that developed in the early to mid-1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically produced short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels.
Pop music According to the website of The New Grove Dictionary of Music and Musicians, called 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".[2] The Oxford Dictionary of Music states that while pop's "earlier meaning meant concerts appealing to a wide audience ... since the late 1950s, however, pop has had the special meaning of non-classical mus[ic], usually in the form of songs, performed by such artists as the Beatles, the Rolling Stones, ABBA, etc".[12] Grove Music Online also states that "... 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'".[2]
