An open mic or open mike (shortened from "open microphone") is a live show at a venue such as a coffeehouse, nightclub, comedy club, strip club, or pub, often taking place at night (an open mic night), in which audience members may perform on stage whether they are amateurs or professionals, often for the first time or to promote an upcoming performance. As the name suggests, performers are usually provided with a microphone plugged into a PA system so that they can be better heard by the audience.
Performers may sign up in advance for a time slot with the host, who is typically an experienced performer or the venue's manager or owner. The host may screen potential candidates for suitability for the venue and give them a time to perform during the show. Open mics are focused on performance arts such as comedy (whether it be sketch or stand-up), music (often acoustic singer-songwriters), poetry, and spoken word. It is less common for groups such as rock bands or comedy troupes to perform, mostly because of the space and logistical requirements of preparing equipment and soundchecking such groups.
