Emo is a style of rock music typically characterized by melodic musicianship and expressive, often confessional lyrics. It originated in the mid-1980s hardcore punk movement of Washington, D.C., where it was known as "emotional hardcore" or "emocore" and pioneered by bands such as Rites of Spring and Embrace. As the style was echoed by contemporary American punk rock bands, its sound and meaning shifted and changed, blending with pop punk and indie rock and encapsulated in the early 1990s by groups such as Jawbreaker and Sunny Day Real Estate. By the mid 1990s numerous emo acts emerged from the Midwestern and Central United States, and several independent record labels began to specialize in the style.
Emo broke into mainstream culture in the early 2000s with the platinum-selling success of Jimmy Eat World and Dashboard Confessional and the emergence of the subgenre "screamo". In recent years the term "emo" has been applied by critics and journalists to a variety of artists, including multiplatinum acts and groups with disparate styles and sounds.
In addition to music, "emo" is often used more generally to signify a particular relationship between fans and artists, and to describe related aspects of fashion, culture, and behavior.
