Stock music is placed in the background of a film, TV or commercial, behind the dialogue or the voice-over. Its purpose is usually to set the mood of the piece but it can also do a number of other things such as highlight a certain section of the narrative, help to identify a location or portray a specific message. In the majority of cases, the piece of music – whether it is a full track or a short sting - has been especially composed for use in one of those genres and is therefore already fit-for-purpose. One of the unique selling points for Stock Music is that it is cheaper than using music from a recognized artist. This is because it is not necessary to obtain specific permission from the composer or pay additional clearance fees when using Stock Music. Stock Music is also considerably less expensive than commissioning a composer to produce a bespoke score, track or jingle specifically for a film, TV or commercial project.
