Glee is an American musical comedy-drama television series that aired on Fox in the United States from May 19, 2009, to March 20, 2015. It centers on the New Directions, a glee club at the fictional William McKinley High School, that is located in the American state of Ohio, which competes as a show choir while its disparate members deal with social issues, especially regarding sexuality, race, family, teen relationships and teamwork.

A glee club in the United States is a musical group or choir group, historically of male voices but also of female or mixed voices, which traditionally specializes in the singing of short songs by trios or quartets. In the late 19th century it was very popular in most schools and was made a tradition to have in American high schools from then on.
