Many new styles of popular music have emerged since rock 'n' roll burst onto the scene in the 1950s.

Rock 'n' roll had a huge cultural impact that united teenagers in the 1950s. In today's world, however, there are many different teenage subcultures and a bigger variety of styles of pop music.

Structure is something that is common to all pop songs, no matter what style it is. Listen out for the verse and chorus in any of your favourite songs. The song may have an introduction and also a middle eight.

Watch this clip of Nina Nesbitt performing 'Masquerade.' Notice when it changes from verse to chorus, as this will help you identify the structure. Nina uses a reverb effect in this song, which is often used in pop tracks.

Contemporary artists are usually influenced by musicians from the past and will sometimes perform cover versions of songs that have been released in the past that they like.

Watch Fatherson perform a cover version of an Elton John's song, 'I'm Still Standing'. Musicians can make their cover version of a song slightly different to the original in order to make it stand out. Fatherson's version of the song adds texture and contrast by adding backing vocals to the songs. Guitars are the dominant instrument, compared to piano in the original version.
