Symphonic metal is a subgenre of metal that tends to use elements normally found in symphonies or Classical Music. That's the basic description of the genre, but its actual implementation can vary widely. The symphonic part can be an entire symphony, a keyboardist, or violin and cello player. The usage of the symphonic elements can vary from trying to create a classical feel, to simply adding thickness to the music. On the softer end are bands where female vocals are frequently used (with bands often featuring female lead vocalists), and acoustic guitars may be included. On the harder end are bands whose style more closely matches Black Metal or another type of Extreme Metal. A band might specialize in Symphonic Metal, or might play a song or album in the style. Of course most metal bands do use classical music scales at least to some extent, but this is about metal bands adopting instruments and movements from the classical music.
Bands of the genre frequently combine symphonic metal with another genre, in most cases either Black Metal, Power Metal, Gothic Metal, or Progressive Metal. In fact, a "pure" symphonic metal band is very hard to find.
Can involve Heavy Mithril.

Tropes that apply to the genre:
- Christian Metal: Antestor.
- Darker and Edgier: Fleshgod Apocalypse, Septicflesh, or Antestor.
- Epic Rocking: Quite common.
- Heavy Mithril: The lyrical theme of most of the bands in the genre.
- Rock Me, Amadeus!: The very foundation of the subgenre.
- Soprano and Gravel: Most symphonic metal bands feature this technique. It's interesting to note that the Soprano tend to be the lead vocals, although Septicflesh and Fleshgod both have it reversed, with the harsh vocals being more prominent.
- Trope Codifier: Nightwish began life as a Power Metal band, but the founders were all classically trained musicians and it didn't take long for them to start incorporating it into their sound, which was hugely influential over the development of the genre. Epica singer Simone Simons was inspired to study classical singing after hearing Tarja Turunen on Nightwish's Oceanborn.
- Trope Maker: Probably Therion, overall. The Trope Maker for symphonic black metal is most likely Emperor, while the Trope Maker for symphonic death is probably Septicflesh.
- Ur-Example: Arguably Concerto for Group and Orchestra, Deep Purple's 1969 collaboration with the Royal Philharmonic Orchestra. It was the first time ever that anyone paired a rock band with major classical instrumentation.
