Partition" is a song recorded by American singer Beyoncé for her self-titled fifth studio album released in 2013. Beyoncé co-wrote and co-produced the song with Justin Timberlake, Timbaland, Jerome "J-Roc" Harmon, Dwane "Key Wane" Weir, and Mike Dean, with extra writing from The-Dream and extra production from Jordy "Boots" Asher. The song was sent to urban contemporary on February 25, 2014 as the third single from Beyoncé by Columbia Records.
The song consists of two parts, individually titled "Yoncé" and "Partition". "Partition" has been described as "electro-R&B" also known as PBR&B that moves "from a sweet, girl-group pop sound to Dirty South hip-hop". Its production musically consists of a sparse synthesized arrangement, a thrusting bassline and a heavy drumbeat giving it elements of electro-R&B. Exploring the deep, sexual nature of Beyoncé, "Partition" depicts sexual intercourse in the back of a limousine. The closing minute of the song features a French word interpolation slightly similar to a quote by actress Julianne Moore in the 1998 film The Big Lebowski.
