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. As such, its position on the Mohs Scale of Rock and Metal Hardness can vary considerably. 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.
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.
- 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
- 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.
