Throughout the history of the British Isles, the land that is now the United Kingdom has been a major music producer, drawing inspiration from church music and traditional folk music, using instruments from England, Scotland, Northern Ireland, and Wales. Each of the four countries of the United Kingdom has its own diverse and distinctive folk music forms, which flourished until the era of industrialisation when they began to be replaced by new forms of popular music, including music hall and brass bands. Many British musicians have influenced modern music on a global scale, and the UK has one of the world's largest music industries. English, Scottish, Irish, and Welsh folk music as well as other British styles of music heavily influenced American music such as American folk music, American march music, old-time, ragtime, blues, country, and bluegrass. The UK has birthed many popular music genres such as beat music, psychedelic music, progressive rock/pop, heavy metal, new wave, industrial music, and drum 'n' bass.
In the 20th century, influences from the music of the United States, including blues, jazz, and rock and roll, were adopted in the United Kingdom. The "British Invasion"—spearheaded by Liverpool band the Beatles, often regarded as the most influential band of all time—saw British rock bands become highly influential around the world in the 1960s and 1970s. Pop music, a term which originated in Britain in the mid-1950s as a description for "rock and roll and the new youth music styles that it influenced", was developed by British artists like Black Sabbath, the Beatles and the Rolling Stones, whom among other British musicians led rock and roll's transition into rock music.
