Warner Music Group (WMG) is the third largest business group and family of record labels in the recording industry, making it one of the big four record companies. For three decades the conglomerate was known as WEA, which stood for Warner Bros.-Elektra-Atlantic Records; three major record companies that signed and developed musical acts and, in turn, distributed product for subsidiaries and other record labels.

The current incarnation of the company as Warner Music Group was formed in 2004 when it was spun off and made completely separate from Time Warner; as a result Time Warner no longer retains any ownership whatsoever in the Warner Music Group, despite its name. WMG also has a music publishing arm called Warner/Chappell Music, which is one of the world's largest music-publishing companies.

In May 2011, the company announced its sale to Access Industries Inc. The purchase of the company was completed on July 20, 2011.

A musical ensemble is a group of people who perform instrumental or vocal music, typically known by a distinct name. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles or wind ensembles. In jazz ensembles, the instruments typically include wind instruments (one or more saxophones, trumpets, etc.), one or two chordal "comping" instruments (electric guitar, piano, or organ), a bass instrument (electric bass guitar or double bass), and a drummer or percussionist. In rock ensembles, usually called rock bands, there are usually guitars and keyboards (piano, electric piano, Hammond organ, synthesizer, etc.) and a rhythm section made up of a bass guitar and drum kit.

In Western Art music, commonly referred to as classical music, smaller ensembles are called chamber music ensembles. The terms duet, trio, quartet, quintet, sextet, septet, octet, nonet and dectet are used to describe groups of two, three, four, five, six, seven, eight, nine and ten musicians, respectively. A group of eleven musicians, such as found in The Carnival of the Animals, is called either a "hendectet" or an "undectet" (see Latin numerical prefixes). A solo is not an ensemble because it only contains one musician.
