cultures make different types of music. Some music goes along with religious ceremonies. Other music is a part of everyday life. The traditional music made by everyday people is called folk music.

Classical music is a formal and artistic music that developed in Europe over hundreds of years. Orchestras, choirs, and chamber ensembles (small groups of musicians) often perform classical music. Opera is a type of classical music that features dramatic singing.

When large numbers of people enjoy a type of music, it is called popular music. Popular music is usually shorter and simpler than classical music. People often buy recordings of popular music or listen to it on the radio. Some of the many types of popular music are rock, country, hip-hop and rap, the blues, jazz, and world music.

What is the other name of “folk music”?
