 typical of rock and metal songs, prog metal bands very often include sections inspired by jazz, classical, Middle Eastern music (especially often using the phrygian dominant scale), Dixieland, ragtime, and many others.This is usually achieved by the keyboard player of the band playing unique sounds, or by including instruments that are unorthodox for metal, such as the saxophone.The idea of incorporating these different kinds of music was primarily pioneered by Dream Theater and it is seen throughout most of their discography.
