"2 Become 1" is a [[pop ballad]] with [[contemporary R&B|R&B]] influences, written in the key of [[F-sharp major|F{{music|sharp}} major]]; it is set in the [[time signature]] of common time and moves at a slow tempo of 72 [[beats per minute]].<ref name="composition">Spice Girls, 2008. pp. 43–47.</ref> The song is constructed in a [[verse–chorus form]],<ref name="composition" /> and its instrumentation comes from a [[guitar]], an [[electronic keyboard]], and [[string instrument]]s.<ref name="album">{{cite AV media notes|title=Spice|title-link=Spice (album)|last=Spice Girls|year=1996|page=6|type=CD booklet|publisher=Virgin Records|id=CDV2812|location=London}}</ref> The song opens with an [[instrumental]] [[introduction (music)|introduction]], with a [[chord progression]] of E{{music|flat}}m add<sub>9</sub>–D{{music|flat}}/F–G{{music|flat}}–A{{music|flat}}m<sub>7</sub> sus<sub>4</sub>, that is also used during the first part of the [[Song structure (popular music)#Verse|verses]]. The last two lines of each verse changes the progression to C{{music|flat}}–B{{music|flat}}m<sub>7</sub>–A{{music|flat}}m<sub>7</sub>–D{{music|flat}}<sub>11</sub>, and changes again during each chorus to G{{music|flat}}–D{{music|flat}}–C{{music|flat}}–D{{music|flat}}.<ref name="composition" /> It closes with a string [[Conclusion (music)#Outro|outro]] that uses the chord progression F{{music|flat}}–G{{music|flat}}–B{{music|flat}}{{music|flat}}–C{{music|flat}},<ref name="composition" /> which is arranged by Scottish composer [[Craig Armstrong (composer)|Craig Armstrong]].<ref>Sinclair, 2004. p. 88.</ref>

The lyrics focus on how the bonding of two lovers can become so strong that they practically become one entity, through the act of [[sexual intercourse]].<ref name="video">Spice Girls, 1997. pp. 38–39.</ref> Apart from the sexual connotations, there is an aspirational undercurrent to the lyrics, and like many of their subsequent songs, desire is explicitly linked to ambition: "Free your mind of doubt and danger/Be for real don't be a stranger/We can achieve it/We can achieve it".<ref name="gerirowe" />

Two different versions of the song, each with different lyrics, were recorded: in the album version, the two first verses are sung by [[Melanie C]] and [[Melanie Brown]], [[Emma Bunton]] sings the pre-choruses, the next second two verses are sung by Melanie C and [[Geri Halliwell]], and the first and third lines of the chorus are sung by Bunton and Halliwell together, the second and fourth lines are sung by Melanie C and [[Victoria Beckham]] together and the fifth line is sung by Brown. The second line of the second verse, "Any deal that we endeavour/Boys and girls feel good together",<ref name="album" /> was changed in the single version to: "Once again if we endeavour/Love will bring us back together".<ref name="single">{{cite AV media notes|title=2 Become 1 - [[Spice Girls]]|date=1996|type=UK CD1 Single liner|publisher=Virgin Records|id=VSCDT 1607}}</ref> Halliwell sings on the album version, while Beckham sings on the single version, after Halliwell confessed that she had a hard time singing in that particular key. Bunton later stated that the lyric change was necessary after realising that the group had become LGBT icons.<ref>{{cite web|url=https://www.gaytimes.com/amplify/emma-bunton-on-the-spice-girls-lyric-they-changed-to-be-more-inclusive-amplify-by-gay-times/|title=Emma Bunton on the Spice Girls lyric they changed to be more inclusive|work=[[Gay Times]]|first=Lewis|last=Corner|year=2019|access-date=3 March 2021}}</ref> Despite the original lyrics still being used in album pressings of ''Spice'', due to the album not being revised since 1997, the single version appeared on the 25th anniversary reissue of the album, in place of the album version. The single version also contains slightly different vocals from the rest of the group.

The single version appears in the music video and is available on the group's ''[[Greatest Hits (Spice Girls album)|Greatest Hits]]'' album, and on stage the girls always performed the single version before and after Halliwell's departure.
