The term "piano lounge" describes a space devoted to live music performed on pianos, but there are many other words that can be used to evoke a similar atmosphere. A "jazz bar" might have a similar vibe, while a "cocktail lounge" suggests a classier, more upscale setting. A "piano bar" specifically indicates that the music will be provided by a piano player, while a "speakeasy" implies a more secretive, underground location. A "piano room" and a "piano salon" suggest a more intimate setting, while a "piano tavern" might evoke a rowdier, traditional pub atmosphere. All of these different phrases suggest a space focused on good music and good company, making them all great synonyms for a piano lounge.
