Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid-1950s . The terms `` popular music '' and `` pop music '' are often used interchangeably , although the former describes all music that is popular and includes many styles . `` Pop '' and `` rock '' were synonymous terms until the late 1960s , when they were increasingly used in opposition from each other .   Although pop music is seen as just the singles charts , it is not the sum of all chart music . Pop music is eclectic , and often borrows elements from other styles such as urban , dance , rock , Latin , and country ; nonetheless , there are core elements that define pop music . Identifying factors include generally short to medium-length songs written in a basic format -LRB- often the verse-chorus structure -RRB- , as well as the common use of repeated choruses , melodic tunes , and hooks .
