Usually production music writers have a decently equipped home recording studio with the ability to compose music that can be sold and licensed to TV networks or advertising agencies. Agencies have a constant need for music of all kinds to go along with TV and radio commercials, so they are always looking for fresh tunes in production music libraries.
After writing a musical score, a successful music composer must be able to record and mix it. Most agencies require broadcast-quality deliverables of a specified length and in a particular format. Although a formal education in music often proves helpful in this profession, music production writers just need the three basic abilities of writing, recording, and mixing music well.
