Description: Cocktail Jazz is a subgenre of jazz music characterized by its smooth, sophisticated, and relaxed ambiance. It emerged in the mid-20th century and became popular in upscale lounges, bars, and restaurants, hence its name. Cocktail Jazz often features small ensembles or soloists playing standards from the Great American Songbook, emphasizing melody, harmony, and improvisation. The music sets a mood that is both elegant and accessible, making it a favorite backdrop for social gatherings, dinners, and events. Artists like Ella Fitzgerald, Frank Sinatra, and Nat King Cole are often associated with this style.
