A floor is the walking surface of a room or vehicle. Floors vary from simple dirt in a cave to many-layered surfaces using modern technology. Floors may be stone, wood, bamboo, metal, or any other material that can hold a person's weight.

The levels of a building are often referred to as floors although a more proper term is storey.

Floors typically consist of a subfloor for support and a floor covering used to give a good walking surface. In modern buildings the subfloor often has electrical wiring, plumbing, and other services built in. Because floors meet many needs, some essential to safety, floors are built to strict building codes in the first world.

Where a special floor structure like a floating floor is laid upon another floor then both may be referred to as subfloors.

Special floor structures are used for a number of purposes:

Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Both terms are used interchangeably but floor covering refers more to loose-laid materials.

Tarja Soile Susanna Turunen Cabuli (born August 17, 1977) is a Finnish singer-songwriter and composer. She is a full lyric soprano and has a vocal range of three octaves.

Turunen studied singing at Sibelius Academy and Hochschule für Musik Karlsruhe. She is well known as a professional classical lied singer but best known as the former lead vocalist of the Finnish symphonic metal band Nightwish, which she founded with Tuomas Holopainen and Erno Vuorinen in 1996. Their combination of hard and fast guitar riffs with Turunen's classical lead vocals quickly achieved critical and commercial popularity. Their symphonic metal style, soon dubbed "opera metal", inspired many other metal bands and singers.

Turunen was dismissed from the band on October 21, 2005 for personal reasons. She started her solo career in 2006 with the release of a Christmas album called Henkäys Ikuisuudesta. In 2007, Turunen released My Winter Storm, an album featuring various styles, including alternative rock and symphonic metal and started the Storm World Tour. Turunen released her third album, What Lies Beneath, in 2010. She performed several concerts in Europe, playing in metal festivals including the Graspop Metal Meeting and the Wacken Open Air, before starting the What Lies Beneath World Tour, scheduled to last until April 2012.

Floor Jansen (pronounced [flɔr ˈjɑnsɛn]; born 21 February 1981, Goirle) is a Dutch soprano singer, who was the lead singer of the symphonic metal band After Forever which disbanded in 2009, and is the current singer for ReVamp.

Jansen was sixteen when she joined Apocalypse (the name of the band After Forever in its early days) in 1997. Three years later the band released its first album, Prison Of Desire. Floor's ability to sing both classical and rock music have made her reasonably popular in the metal scene. She took sole charge of After Forever's lyrics and vocal melodies since the departure of Mark Jansen (no relation) in 2002. Prior to this, up until the Decipher album, the two would write together.

Floor started studying music at the Dutch Rock Academy in 1999 and entered the conservatory three years later. She studied Musical Theatre and one year of Opera. Later on, she started teaching performing in her own course called Wanna be a Star?!.
