The music of progressive metal features complex, layered arrangements in longer than typical songs, often including lengthy instrumental passages allowing the performers to display technical proficiency and interplay. Many time signature changes are common, as is the incorporation of Western classical music influences. The sound is generally driven by the guitars and drums, but it is quite typical to add elements non-standard to rock or metal such as synthesizers and an array of orchestral elements.

Progressive metal vocals often feature operatic, high-register vocals, but sometimes this is not the case. Progressive metal, being such an experimental genre, has seen all sorts of spin-offs and new takes. Extreme progressive metal is any form of progressive metal that takes influence from thrash, death, black, doom, or other genres of metal that are considered "extreme."
