Bespoke Music refers to a service provided by a composer, where music is custom-made to the commissioner's specification.
Whilst most music is bespoke in its inception, the term bespoke music usually describes a process initiated by an individual or group that requires new music for a specific purpose. Examples include advertising organisations who need music to specifically accompany a TV or Radio orientated advert, film makers that need a score to underpin their footage and brands that require a musical ID to distinguish their product.
