A karaoke host acts as an MC or DJ for a special event, such as a wedding, or as ongoing entertainment at a venue. Your duties in this career include engaging with the crowd to encourage them to sing a song. You also select music to keep the party atmosphere going in between participants. You may travel to different sites for a one-off performance or gig or have several recurring events that you do every week. As a self-employed karaoke host, you must maintain your equipment and ensure that your library of recordings is up-to-date. You need to have a screen for the performer, microphones, and a sound system if the venue does not have one.
