Pop music is a form of popular music that originated in the United States and Great Britain during the late 1940s and early 1950s. On the other hand, Disco is a genre of dance music and a subculture that emerged in the 1970s from the United States' urban nightlife scene.

This genre of music has changed dramatically over time from one genre to another. The term "pop music" was first used around 1900, but it became more common in the 1930s to describe a new style of music. 

Even if that time limit may have been increased a little in recent years, the other characteristics of pop singles have mostly remained the same. Popular music has been an important part of Western culture since at least the mid-20th century. The development of recording technology has made it easier for performers to create recordings that sound similar to one another (and therefore commercially successful).

Pop music began as an American phenomenon, with bands like the Beach Boys, the Mamas and the Papas, and The Shangri-Las 

giving listeners songs to dance to.

Pop music is generally characterised by a verse-chorus structure, an emphasis on melody over rhythm, and often features accompaniment by electric guitars or electronic keyboards.
