Glee is an American musical comedy-drama television series produced by Fox. It focuses on the glee club New Directions, at the fictional William McKinley High School in Lima, Ohio.[1] The show was created by Ryan Murphy, Brad Falchuk and Ian Brennan, and features many cover versions of songs sung on-screen by the characters.[2] Murphy is responsible for selecting all of the songs used, and strives to maintain a balance between show tunes and chart hits, as he wants there to be "something for everybody in every episode."[3] Once Murphy selects a song, rights are cleared with its publishers by music supervisor P.J. Bloom, and music producer Adam Anders arranges it for the Glee cast.[4] Numbers are pre-recorded by the cast; studio recordings of tracks are then made. The process begins six to eight weeks before each episode is filmed, and can end as late as the day before filming begins.[4] The list below contains all 73 musical performances of the sixth season, with each performance delivering an individual song or a mashup of two or more songs in a single performance.
