"Big Love" explores the skepticism of entering a romantic relationship. It originally stemmed from a feeling of isolation, written by Lindsey Buckingham while living alone in a house on a hill in Bel Air. Though initially intended for a solo album, the song was nearly complete when it was brought to Fleetwood Mac's Tango in the Night. The track is built around a main guitar riff, bass, and a mix of programmed and live drums, with Buckingham even performing the "oh-ah" vocals himself using a variable speed oscillator. Playing it channels that raw, hesitant energy of love's potential amidst solitude.
