Jobs at a piano bar include bartenders and servers who are employees of a piano bar, as well as the performers who play for the bar. A bartender’s duties include mixing and serving drinks to customers and keeping a running tally of their bill. Wait staff attends to customer tables to take orders, serve food and drink, and answer questions. The responsibilities of piano performers are to play piano and sing as part of the live entertainment for the bar. Bartender and server positions can be part-time or full-time, while performers usually work part-time for special gigs or one-time performances.
