Progressive rock
Progressive rock bands write and play songs that have many changes during each song. Regular rock songs have verses and a chorus, but progressive songs can have many different sections. For example, instead of having verses and choruses, progressive rock songs may have many different musical themes, solos, and musical moods. A typical progressive song might have a form such as: Introduction-Verse-Chorus-instrumental section-New verse-New chorus-Instrumental section-Ending.
