What is the difference between popular music and other genres?

popular music is also known as pop music which is music that is current and very popular in the time period that it was released in. the meaning of pop music changes as we enter different decades, e.g.pop music in the 60s were bands such as the Beatles(haha) and we today have a complete different understanding of pop music. whereas other genres such as rock or jazz, all have a specific, recognisable sound and that have certain features associated with the genre e.g. jazz music has alot of ornamentation in it, and this is a set feature that will always be associated with jazz music.

hope this helps ya! :)
