The evolution of music in the UK can be divided into several periods: Baroque music from the early modern period was characterized by elaborate ornamentation and new genres like opera; classical music in the 18th century inherited European traditions; romantic nationalism in the 19th century encouraged distinct national identities seen in composers like Elgar; folk music traditions vary across England, Northern Ireland, Scotland, and Wales; modern popular music has flourished in Britain since the 20th century, influenced by genres like folk, jazz, and rock with early influences from the US.
