Musicians usually book gigs through their agents or managers, who negotiate the terms and conditions of the performance with the venue or event organizer. Gigs can provide musicians with opportunities to showcase their talent, build their fan base, and earn income from their music.
The term "gig" can also be used more broadly to refer to any job or project that a musician may undertake for compensation. For example, a musician might do a studio session or write music for a commercial as a gig.
