B.B.B.F.F. (Big Brother Best Friend Forever) is a song that is featured in the episode A Canterlot Wedding - Part 1. Twilight Sparkle first sings it when she explains to her friends that her brother, Shining Armor, was the only pony she trusted as a friend before she was sent to Ponyville. Later in the episode, when she was afraid she had "lost a brother" because of an argument, she sings a somber, much shorter reprise. The song is notable in being Twilight's first solo song. Meghan McCarthy stated that she was inspired by the relationship her daughter has with her older brother.
The song's composer, Daniel Ingram, used a cadence known as a "deceptive cadence" rather than an "authentic cadence" to finish the reprise as an "inside joke". The non-reprisal version ends on an authentic cadence, D flat major, rather than a deceptive one (B flat minor). In a (now deleted) tweet, Daniel Ingram mentions that Rebecca Shoichet was lightly autotuned to produce a "harmonizing effect."
This song is the ninth track on the Songs of Friendship and Magic soundtrack album, although the liner no...
