Symphonic rock

Symphonic rock is a subgenre of progressive rock. Since early in progressive rock's history, the term has been used to distinguish more classically influenced progressive rock from the more psychedelic and experimental forms of progressive rock.

Symphonic rock can be described as the combining of progressive rock with classical music traditions. Some artists perform rock arrangements of themes from classical music or compose original pieces in classical composition structures. Additionally, they may play with the accompaniment of a symphony orchestra or use a synthesizer or mellotron to emulate orchestral instruments.

As the term is used in music criticism (and this article), orchestral renditions of hit rock and pop songs do not necessarily qualify as symphonic rock, though various outlets sometimes market them using that term. Using an orchestra does not make a piece symphonic rock; it must meet the criteria for being progressive rock in addition to the qualities listed for being symphonic.
