Pop is a genre of popular music that emerged in its modern form in the mid-1950s in the United States and Britain.
The terms popular music and pop music are often used interchangeably;
The former, however, describes all the music that is popular and includes many different styles.
During the 1950s and 1960s, pop music, rock and roll, and youthful styles were influenced.
Rock and pop remained almost synonymous until the late 1960s, when pop became associated with commercial, fleeting, and accessible music.
Iranian pop music was transformed by the arrival of singers such as Wigan and the use of various instruments with Western styles and entered a new arena.
Wigan is one of the first famous Iranian singers to play the guitar in Iranian pop music and is also known as the king of Iranian jazz.
Iranian pop music was also formed during the Qajar period and in the nineteenth century, and after the advent of radio, it expanded significantly.
Before the 1950s, the Iranian music market was in the hands of classical music singers.
