British dance band is a genre of popular jazz and dance music that developed in British dance halls and hotel ballrooms during the 1920s and 1930s, often called a Golden Age of British music, prior to the Second World War.

A golden age is a period considered the peak in the history of a country or people, a time period when the greatest achievements were made. The term originated from early Greek and Roman poets, who used it to refer to a time when mankind lived in a better time and was pure.
