Pop music is a genre of popular music that evolved from rock and roll in the 1950s. Pop music and popular music are often interchangeably utilized, even though the latter refers to music which is well-known and popular while the former is a particular genre which contains qualities of mass appeal. Pop music started its evolution around the mid-1920s, when jazz and pop were at their peak. A lot of things that took place in the recordings of that era reflected as being the start of the modern day pop music, which includes, country, folk, rhythm and blues music and others.
Though pop music is basically seen as the singles charts, it does not refer to the entirety of all chart music. Pop music is defined by its eclectic nature and usually borrows elements from other styles such as dance, urban, rock, country, and Latin. Nevertheless, there are vital factors and elements which define pop music. These factors include the structure of the song which is generally short to medium-length songs written in a verse-chorus structure, as well as the frequent use of melodic tunes, repeated choruses, and hooks.
The major medium of pop music is the song itself, which has an average duration of two to four minutes and is generally marked by a noticeable and consistent rhythmic element, a simple traditional structure and a mainstream style. It is usually marked with the verse-chorus form, with a focus on catchy hooks and melodies, and a chorus with contrasting melody, rhythm, and harmony with the verse. The melodies and beats are usually simple, accompanied by a small harmony. The lyrics of modern pop songs usually focus on themes such as romantic relationships and love, and a variety of other things. Some of the notable artistes that have carved a niche for themselves in the world of pop music include Michael Jackson, Madonna, Lionel Ritchie, Bruno Mars, Adele, Beyonce, Justin Bieber, Ed Sheeran, Elton John, Usher, Celine Dion and a host of others.
