A piano bar (also known as a piano lounge) consists of a piano or electronic keyboar played by a professional musician, located in a cocktail lounge, bar, hotel lobby, or office building lobby. Usually the pianist receives tips in a jar or basket on or near the piano, especially from patrons requesting a song. Some piano bars feature a baby grand or grand piano surrounded by stools for patrons (or, somewhat humorously, an upright piano covered by a counter that makes it appear to be a grand piano). Others have a bar surrounding the piano or keyboard.
